If he p-value is used for hypothesis testing , then the Null Hypothesis is rejected if (a) p-value ≤ α .

In a hypothesis testing, the p-value represents the probability of observing a test statistic as extreme or more extreme than the one observed, provided that the null hypothesis is True.

The significance level, represented by "α" , is a pre-determined threshold which determines the level of evidence required to reject the null hypothesis.

If the p-value is less than or equal to α, this indicates that the observed test statistic is sufficiently unlikely to occur under the null hypothesis, and therefore the null hypothesis is rejected.

Therefore , the Null hypothesis is rejected if (a) p-value ≤ α .

The correct answer is a) p-value ≤ α. In hypothesis testing, the null hypothesis is typically assumed to be true initially. The p-value is used to determine the probability of observing a test statistic as extreme or more extreme than the one obtained from the data, assuming that the null hypothesis is true.

The significance level (α) is chosen beforehand and represents the maximum acceptable probability of rejecting the null hypothesis when it is actually true.

If the p-value is less than or equal to the significance level (p-value ≤ α), then the result is considered statistically significant and the null hypothesis is rejected. This implies that the observed effect is unlikely to have occurred by chance alone and that the alternative hypothesis is more likely to be true.

list2 = [6.04, 0.08, -1.15, 0.46, 3.62, 1.28, -2.99, 6.09, -0.47, 1.12]
list3 = [4, 2, 1, 1, 2, 3, 2, 3, 5, 4], then Python program to create a dictionary with keys 1,2,3,... and the values being each element from the three lists, to generate a 4th list with all values < -1.00 or values > 2.00 in list1 but whose corresponding values from list3 are larger than 1, to generate  a 5th list with all values < -0.50 or values > 1.30 in list2 but whose corresponding values from list3 are larger than 1 and to build a sixth list with the values of list 1 that match to the dictionary values obtained in list4 and list5 can be written.

1) Python program to create a dictionary with keys 1, 2, 3,... and the values being each element from the three lists:
my_dict = {}
for i in range(len(list1)):
   my_dict[str(i+1)] = [list1[i], list2[i], list3[i]]

print(my_dict)

2) To generate a 4th list with all values < -1.00 or values > 2.00 in list1 but whose corresponding values from list3 are larger than 1, we can use a for loop with an if condition:

list4 = []
for i in range(len(list1)):
   if (list1[i] < -1.00 or list1[i] > 2.00) and list3[i] > 1:
       list4.append(list1[i])

print(list4)

3) The python program to generate a 5th list with all values < -0.50 or values > 1.30 in list2 but whose corresponding values from list3 are larger than 1:

       list5.append(list2[i])

print(list5)

4) Finally, to build a sixth list with the values of list 1 that match to the dictionary values obtained in list4 and list5, we can use the following code:

list6 = []
for value in my_dict.values():
   if value[0] in list4 and value[1] in list5:

Answer:

Step-by-step explanation:

If A is similar to B, and A is invertible, then B is also invertible and the inverse of A, denoted as A^(-1), is similar to the inverse of B, denoted as B^(-1). This can be proved by showing that B^(-1) = (P^(-1))^(-1) A^(-1) P^(-1), where P is the invertible matrix that relates A and B.

Given that A is similar to B, we have B = P^(-1)AP for some invertible matrix P. If we multiply both sides of this equation by P, we get BP = P(P^(-1)AP). Since P^(-1)P is the identity matrix, we have BP = (PP^(-1))AP, which simplifies to BP = A.This shows that B is invertible, with B^(-1) = P^(-1)AP.

If a student was randomly chosen from the middle school of rock, there is a 20% chance that they would be playing the drums.

Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

The probability that a student chosen at random will play the drums can be calculated by dividing the total number of drum players by the total number of students in both grade levels.

For this calculation, we will consider the total number of students in both grades, which is 70 (5+12+14+4+12+5+10+8).

Therefore, the probability of a student chosen at random playing the drums can be calculated as follows:

(14 Drum Players/70 Total Students) x 100 = 20%

Rounded to the nearest whole number, the probability of a student chosen at random playing the drums is 20%.

The example that illustrates the difference between statistical significance and practial significance is

In a survey arranged by school-authority of a district on participation in sports by school-going boys and girls, it is found that 60% of boys and 57% of girls participate in outdoor sports. Thus the survey shows a 3% difference between school-going boy-participants and girl-participants in outdoor sports. Now the point is how much significance this 3% difference has statistically as well as practically. Statistical significance of this 3% depends upon the size of data used in determining the percentage of boys and girls participate in sports. If a sufficiently big sample size is used then the difference is statistically significant, and if a very small sample size is used then the difference is statistically insignificant. Thus bigger the sample size more is the statistical significance of a computed figure.

On the other hand practical significance of this 3% difference arises if decision is made or action is taken or needs to be taken on the basis of this 3% difference. If cost permits, the authority may consider promoting girl students participation in sports in order to bring about more gender parity in outdoor sports. In this case the 3% difference though small, may be practically significant.

Step-by-step explanation:

Zeros of a polynomial function are its x-intercepts, the values of x that make the polynomial zero. Each zero x=p corresponds to a linear factor (x-p) of the polynomial.

A monic polynomial is one that has a leading coefficient of 1. For a monic polynomial of degree n, the coefficient of the term of degree n-1 is the opposite of the sum of all of the zeros. The constant term of any odd-degree monic polynomial is the opposite of the product of the zeros.

The given polynomial can be made monic by dividing by its leading coefficient:

  (2x^3 -x^2 -5x -2)/2 = x^3 -(1/2)x^2 -(5/2)x -1

The given polynomial has degree 3, so we're interested in the coefficient of the x^2 term. That coefficient is -1/2, so the sum of zeros will be ...

  sum of zeros = -(-1/2) = 1/2

If z represents the third zero, then we have the sum ...

  1/2 = -1 +2 +z

  z = -1/2 . . . . . . subtract 1 from both sides

The third zero is -1/2.

The given polynomial is of odd degree, so the product of the zeros is the opposite of the constant.

  (-1)(2)(z) = -(-1)

  z = 1/(-2) = -1/2 . . . . . divide by the coefficient of z

The third zero is -1/2.

Of course, a graph will show all of the (real) zeros. The attached graph from a graphing calculator shows the third zero is -1/2.

Perimeter is a measure of the distance around the boundary of a two-dimensional shape. It is the total length of all the sides or edges of a shape. For example, if you have a rectangle with a length of 5 units and a width of 3 units, the perimeter would be:

2(5 + 3) = 2(8) = 16 units

In this case, we added up the lengths of all four sides of the rectangle to get the perimeter.

Perimeter is typically measured in units of length, such as meters, feet, or centimeters, depending on the context of the problem. It is an important concept in geometry and is used to calculate the amount of material needed for things like fencing or paving.

Now to find the total length of the fence required, we need to find the perimeter of the garden. We can break the garden into two parts: the rectangle and the semicircle.

The rectangle has a length of 30 feet and a width of 23 feet, so its perimeter is:

2(30) + 23 = 83 feet

The semicircle has a diameter equal to the width of the rectangle (23 feet), so its radius is half of the diameter, or:

r = 23/2 = 11.5 feet

The circumference of the semicircle is half of the circumference of a full circle with the same radius, so it is:

(1/2) * 2 * 3.14 * 11.5 = 36.07 feet (rounded to two decimal places)

To find the total perimeter, we add the perimeter of the rectangle and the circumference of the semicircle:

83 + 36.07 = 119.07 feet

Therefore, the gardener needs 119.07 feet of fence to surround the rose garden.

The function y = \(x^2(x^2 - 6x + 9)\)has zeros at x = 0 and x = 3, indicating that it has distinct real zeros and no complex zeros.

The function \(y = x^2(x^2 - 6x + 9)\) has zeros at x = 0 and x = 3, indicating it has distinct real zeros and no complex zeros.

In the second paragraph, we explain the answer in 120 words: To determine the zeros of the function, we set y = 0 and solve for x.

The expression \(x^2 - 6x + 9\) can be factored as\((x - 3)^2\), so the function can be rewritten as \(y = x^2(x - 3)^2\).

This shows that the function has a zero at x = 0 (from the \(x^2\) term) and another zero at x = 3 (from the (x - 3)^2 term). Since both zeros are real and distinct, we conclude that the function has distinct real zeros.

Furthermore, there are no complex zeros because the function does not involve any complex numbers or imaginary units.

Therefore, the function \(y = x^2(x^2 - 6x + 9)\) has distinct real zeros but no complex zeros.

The acceleration vector of the car at time t=1 is -18i + 2e²j, where i and j are the unit vectors in the x and y directions, respectively. The position of the car at time t=2 is (5.52, 9.86) feet.

To find the acceleration vector of the car at time t=1, we need to find the derivative of the velocity vector v(t) with respect to time t:

a(t) = d/dt [3+6sin(3t)]i + d/dt [1+e²t]j

= 18cos(3t)i + 2e²j

Plugging in t=1, we get:

a(1) = 18cos(3)(1)i + 2e²j

= -18i + 2e²²j

To find the position of the car at time t=2, we need to integrate the velocity vector v(t) from t=0 to t=2:

r(t) = \(\int_{v(0)}^{v(t)} v(u) du\)

where v(u) = {3+6sin(3u),1+e²u}.

We can integrate each component of the velocity vector separately:

x(t) = \(\int_0^t (3+6sin(3u)) du\) = 3t - 2cos(3t) + 2

y(t) = \(\int_0^t (1+e^2u) du\) = t + (1/2)e²t

Plugging in t=2, we get:

x(2) = 3(2) - 2cos(3(2)) + 2 ≈ 5.52 feet

Subtracting 11/2 from both sides:

5 8 h = 5 - 1 1 2

Simplifying:

5 8 h = 8 1 2

Dividing both sides by 5/8:

h = 8 1 2 ÷ 5 8

Converting the mixed number to an improper fraction:

h = (8 x 8 + 1) ÷ 5 8

h = 65/8

Now, we can convert this fraction to a mixed number:

The speed of the faster cyclist is 14\ miles/hr.

What is speed?

It is the average distance coverd in unit time. It is also defined as the rate of change of distance with respect to time.

Since the speed of the first cyclist is double than the second cyclist hence, the first cyclist will cover the double distance than the second cyclist. Consider the first cyclist covers 2s distance and first cyclist covers s distance. The sum of these two distances should be 42 miles. Hence,

\(2s+s=42\\3s=42\\s=14\)

Now, distance coverd by the first cyclist is \(2s=2\times 14\\=28 \ $miles\).

Now, both the cyclists meet after 2 hr hence, time taken by the first cyclist is 2 hr.

\(Speed=\frac{Total\ distance}{Total\ time}\\=28\ miles/2 \ hr\\=14\ miles/hr\)

Hence, the speed of the faster cyclist is 14\ miles/hr.
