Thus,  the higher the test statistic, the stronger the evidence against the "null hypothesis" (i.e., no relationship between Alcohol and Calories).

To calculate the test statistic for the relationship between Alcohol (X) and Calories (Y) in the Beer Large data set, you'll need to perform a linear regression analysis.

1. Access the Beer Large data set in StatCrunch and load it into the platform.
2. Select 'Stat' > 'Regression' > 'Simple Linear' from the menu.
3. Choose 'Alcohol' as the explanatory variable (X) and 'Calories' as the response variable (Y).
4. Click 'Compute' to run the linear regression analysis.

The output will provide you with the test statistic value (rounded to 1 decimal place) for the relationship between Alcohol and Calories.

This value is important when assessing the significance of the relationship between the two variables, as it helps you determine if the relationship is statistically significant or not.

Remember, the higher the test statistic, the stronger the evidence against the null hypothesis (i.e., no relationship between Alcohol and Calories).

The value of the expression "true && !false" can be determined by evaluating each part separately and then combining the results.

1. The "!" symbol represents the logical NOT operator, which negates the value of the following expression. In this case, "false" is negated to "true".

2. The "&&" symbol represents the logical AND operator, which returns true only if both operands are true. Since the first operand is "true" and the second operand is "true" (as a result of the negation), the overall expression evaluates to "true".

Therefore, the value of the expression "true && !false" is "true".

After reducing all the book prices by 50%, the new median price is determined to be $7.70 (B)

To find the new median price after reducing all the book prices by 50%, we first need to calculate the reduced prices. By reducing each given price by 50%, we get $6.375, $7.40, $9.995, $4.975, $8.00, and $8.975 respectively.

Next, we arrange these reduced prices in ascending order: $4.975, $6.375, $7.40, $8.00, $8.975, and $9.995. The median is the middle value in this ordered list. Since there are six prices, the middle two values are $7.40 and $8.00.

To find the median, we take the average of these two values, which gives us ($7.40 + $8.00) / 2 = $7.70.

Therefore, the new median price, after reducing all the book prices by 50%, is $7.70 (B). This means that the median price of the books, after the reduction, is $7.70.

The cost for question 8e is $35.

In order to determine the cost for question 8e, we need to consider the table provided in the question. The table presents the cost of purchasing a device from two different websites, with one website offering a discounted price for the device.

The table also includes the cost of shipping and handling (S&H) for each website.The cost for question 8e can be calculated as follows:Cost = (Price + S&H) - DiscountThe website offering a discounted price for the device is Website B, where the device costs $160.

However, Website B charges a higher S&H fee of $15. Therefore, the total cost of purchasing the device from Website B is $160 + $15 = $175.The website offering the device at its regular price is Website A, where the device costs $200.

However, Website A charges a lower S&H fee of $10. Therefore, the total cost of purchasing the device from Website A is $200 + $10 = $210.To determine the cost for question 8e,

we need to find the difference between the total cost of purchasing the device from Website A and Website B.

This can be calculated as follows:Cost = Total cost from Website A - Total cost from Website BCost = ($200 + $10) - ($160 + $15)Cost = $210 - $175Cost = $35

Answer:

The 3rd answer because each income has an outcome.

Step-by-step explanation:

Answer:

4th option is correct.

Answer:

Yes, because each x-value corresponds to one y value.

Step-by-step explanation:

If you look at the table, you notice that there is one output (y) for every input (x). This means that it is a function. It would NOT be a function if you had two outputs for an input. For example, there are two x values that are 6. For one coordinate pair, the table says (6,9) and (6,8). Since there are two values for the same input- it wouldn't be a function. In this case, there is an input of 4 and 5 with the same output. That is okay! Even though they have the same y value, those inputs still only have ONE output.

The 95% confidence interval for population mean is (19.8, 22.2).

The confidence interval for population mean using the Student's t-distribution is:

CI = x ± \(t_{\frac{\alpha }{2}, (n -1) }\) \(\frac{s}{\sqrt{n} }\)

Given:

x = 22

s = 3

n = 27

α = n - 1 = 26

The critical value of t for α = 0.05 and degrees of freedom, (n - 1) = 19 is:

\(t_{\frac{\alpha }{2} , (n -1)}\) = \(t_{\frac{0.05}{2,19} }\)

            = 2.093

Compute the 95% confidence interval for population mean as follows:

   CI = X + \(t_{\frac{\alpha }{2}, (n -1) }\frac{s}{\sqrt{n} }\)

⇒ CI = 21± 2.093 × 3/√27

Answer:

y = 4x - 15

Step-by-step explanation:

Find slope (m) using of the line that passes through (7, 13) and (4, 1).

\( slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 13}{4 - 7} = \frac{-12}{-3} = 4 \)

Find y-intercept (b) by substituting x = 4, y = 1, and m = 4 in y = mx + b.

Thus:

1 = (4)(4) + b

1 = 16 + b

Subtract 16 from each side

-15 = b

b = -15

substitute m = 4, and b = -15 in y = mx + b, to get the equation.

By using a maclaurin series to obtain the maclaurin series for the given function is  F(x) = x cos(5x) = \(1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...\)

To obtain the Maclaurin series for the function f(x) = x cos(5x), we need to write the Maclaurin series for cos(5x). The Maclaurin series for cos(x) is: \(cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! + ...\)

Using this formula, we can substitute 5x for x and obtain the Maclaurin series for cos(5x): cos(5x) =\(1 - (5x)^2/2! + (5x)^4/4! - (5x)^6/6! + ...\)

\(= 1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...\)

We can substitute this series into the original function f(x) = x cos(5x) and obtain its Maclaurin series: f(x) = x cos(5x)

\(= x[1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...]\)

\(= x - 25x^3/2! + 625x^5/4! - 15625x^7/6! + ...\)

This is the Maclaurin series for the function f(x) = x cos(5x). It is obtained by substituting the Maclaurin series for cos(5x) into the original function and simplifying the resulting series. Maclaurin series are useful for approximating functions using polynomials. By truncating the series after a certain number of terms, we can obtain a polynomial that approximates the original function to a certain degree of accuracy. The accuracy of the approximation depends on the number of terms in the series that are used. The more terms we include, the more accurate the approximation will be.

Answer:

Jenny´s age is 19 and her mother is 43.

Step-by-step explanation:

Given that

x + 2x + 5 = 62

where,

x = Jenny’s age

Now the following cases occured

a.  

x = 12

Now put the x value to the above equation

12 + 2(12) + 5 = 62

12 + 24 + 5 = 62

41 = 62

It is not equaled so the Jenny age is not 12

b.

x = 15

Now put the x value to the above equation

12 + 2(15) + 5 = 62

15 + 30 + 5 = 62

50 = 62

It is not equaled so the Jenny age is not 15

c.  

x = 18

Now put the x value to the above equation

18 + 2(18) + 5 = 62

18 + 36 + 5 = 62

59 = 62

It is not equaled so the Jenny age is not 12

d.

x = 19

Now put the x value to the above equation

19 + 2(19) + 5 = 62

19 + 38 + 5 = 62

62 = 62

It is equaled so the Jenny age is 19

Now the mother age is

as we know that

x + y = 62

19 + y = 62

y = 62 - 19

= 43

Also it proved that if we doubles the jenny age i.e 38 and then add 5 so the total is 43 i.e. equivalent to her mother age

Required sum of the other two numbers is 15.

What is average?

In mathematics, the average is a measure that represents the typical value of a set of numbers. It is calculated by adding up all the numbers in the set and then dividing by the total number of values in the set. The average is also known as the arithmetic mean.

Here we can let the two unknown numbers that we need to find "x" and "y".

We know that the average of 5 numbers is 9, so the sum of those 5 numbers is (5 x 9) = 45

We also know that the sum of three of those numbers is 30. So, we can write an equation:

x + y + z = 30 where "z" represents the sum of the other two numbers.

We can solve for "z" by subtracting x and y from both sides:

z = 30 - x - y

We also know that the sum of all 5 numbers is 45, so we can write another equation:

x + y + z + w + v = 45

where "w" and "v" represent the other two numbers.

We can solve for "w + v" by substituting the expression we found for "z" into this equation:

x + y + (30 - x - y) + w + v = 45

Simplifying this equation, we get:

w + v = 15

So, the sum of the other two numbers is 15.
