True or False: Suppose you are interested in estimating following SLR model: Further suppose that is your estimate of that you generated using a supposedly brand new estimation method called Extraordinary Least Squares (ELS). The sampling distribution for is equal to the true 50% of the time. This new estimate of using ELS is unbiased.

Answers

Answer 1

False.  If the sampling distribution for is equal to the true value only 50% of the time, the estimate generated using ELS is not unbiased.

The statement is contradictory.

1. The sampling distribution for is equal to the true value 50% of the time: This means that when you repeatedly sample from the population and estimate using ELS, only 50% of the estimates will equal the true value. In other words, the ELS estimation method is inconsistent because it provides accurate estimates only half of the time.

2. This new estimate of using ELS is unbiased: Unbiasedness refers to the property of an estimation method where, on average, the estimates obtained are equal to the true value. However, if the sampling distribution for is equal to the true value only 50% of the time, it means that the estimates, on average, deviate from the true value. In other words, the ELS estimate is biased because it consistently tends to overestimate or underestimate the true value, resulting in an average deviation from the true value.

In summary, if the sampling distribution for is equal to the true value only 50% of the time, the estimate generated using ELS is not unbiased.

The measures of the larger angles are __°, and the measures of the smaller angles are __°

The measures of the larger angles are __, and the measures of the smaller angles are __

Answers

The measures of the larger angles are 130°, and the measures of the smaller angles are 50°

How to find the measures of angles?

Vertically opposite angles are angles that shares the same vertex point . Vertically opposite angles are congruent.

Therefore, the angles 3y + 11 and 4x - 22 are vertical angles and 10y and 7x + 4 are vertical angles.

Hence,

10y = 7x + 4

10y - 7x = 4

3y + 11 = 4x - 22

3y - 4x = - 33

Combine the equation

10y - 7x = 4

3y - 4x = - 33

multiply equation(ii) by 1.75

10y - 7x = 4

5.25y - 7x = - 57.75

subtract the equation

4.75y = 61.75

y = 61.75 / 4.75

y = 13

Therefore, let's find x

10(13) = 7x + 4

130 - 4 = 7x

7x = 126

x = 126 / 7

x = 18

Hence,

10y = 10(13) = 130 degrees

(3(13) + 11) = 50 degrees

Therefore,

larger angle = 130°

smaller angle = 50°

congruent to A'B'C'. Explain your reasoning.

Answers

Answer:

ΔABC and ΔA'B'C' are congruent, by the SSS rule of congruency

Step-by-step explanation:

The given parameters are;

The transformation undergone by triangle ABC = (x, y) → (x + 7, y + 3) to give triangle A'B'C'

Therefore, the points on triangle ABC are transformed by a translation of 7 units to the right and 3 units up to form triangle A'B'C'

Given that a translation transformation is a form of rigid transformation, we have;

The lengths of triangle ABC are congruent to the lengths of the sides of triangle A'B'C'

Therefore. ΔABC ≅ ΔA'B'C', by the Side-Side-Side (SSS) rule of congruency.

Deterministic time Calculate a best upper bound (in Big O notation) on the expected running-time for generating random numbers p and g as described below: - pick a random m-bit integer q until p:=2q+1 is declared an (m+1) -bit Sophie-Germain prime. For simplicity, assume that Miller−Rabin(N,t) ran on a composite number N declares prime with probability exactly 4 −t
. - pick a random integer g,1≤g≤p−1, a primitive element of F p

. 1) Establish the value ϕ(p−1) as a function of q. 2) Express your expected time bound as a function of m and t. Assume all primality testing is done via Miller-Rabin (N,t) at cost O(m 3
t) time. Assume the probabilities that q and p be prime are independent.

Answers

In conclusion, the expected running time for generating random numbers p and g can be expressed as a function of m and t as follows:

\(O((1/(m ln(2))) * (m^3t)) = O(m^2t/ln(2))\)

The expected time for generating the prime number p depends on the probability of q being prime and the number of iterations required to find a Sophie Germain prime. Since q is an m-bit integer, the probability of q being prime is approximately \(1/ln(2^m) = 1/(m ln(2)).\)

The cost of performing Miller-Rabin primality testing on a composite number N is O(\(m^3t\)) time, as stated in the problem. Therefore, the expected time to find a prime q is proportional to the number of iterations required, which is 1/(m ln(2)).

Finding a primitive element g within the range 1 ≤ g ≤ p-1 involves randomly selecting integers and checking if they satisfy the condition. Since this step is independent of the primality testing, its time complexity is not affected by the value of t. Therefore, the expected time to find a primitive element g is not directly influenced by t.

a. (5) The demand function for a good X is Qx= m-3Px+2Py, where m is income, Px is the price of X, Py is the price of a related good Y and Qx is the demand for X. Income and prices are all positive. X

Answers

The demand function for good X is Qx = m - 3Px + 2Py, where Qx is the quantity demanded of X, m is income, Px is the price of X, and Py is the price of a related good Y. The equation shows that the demand for X is inversely related to its price and directly related to the price of Y. Income, price of X, and price of Y collectively affect the overall demand for X.


The demand function for good X is given by Qx = m - 3Px + 2Py, where Qx represents the quantity demanded of good X, m is the income, Px is the price of good X, and Py is the price of a related good Y. In this equation, the income and prices are assumed to be positive.

To determine the demand for good X, we can analyze the equation. The coefficient -3 in front of Px indicates that the demand for good X is inversely related to its price. As the price of X increases, the quantity demanded of X decreases, assuming other factors remain constant. On the other hand, the coefficient 2 in front of Py indicates that the demand for good X is directly related to the price of the related good Y. If the price of Y increases, the quantity demanded of X also increases, assuming other factors remain constant.

Furthermore, the term (m - 3Px + 2Py) represents the overall effect of income, price of X, and price of Y on the quantity demanded of X. If income (m) increases, the quantity demanded of X increases. If the price of X (Px) increases, the quantity demanded of X decreases. If the price of Y (Py) increases, the quantity demanded of X increases.

A distribution of values is normal with a mean of 90 and a standard deviation of 20. From this distribution, you are drawing samples of size 35. Find the interval containing the middle-most 48% of sample means: Enter your answer using interval notation. In this context, either inclusive or exclusive intervals would be acceptable. Your numbers should be accurate to 1 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

Answers

The interval containing the middle-most 48% of sample means is approximately [88.23, 91.77] (using interval notation).

To find the interval containing the middle-most 48% of sample means, we can use the Central Limit Theorem and the properties of the standard normal distribution.

Since the sample size is large (n = 35), we can approximate the distribution of the sample means to be normal with a mean equal to the population mean (μ = 90) and a standard deviation equal to the population standard deviation divided by the square root of the sample size (σ/√n = 20/√35 ≈ 3.38).

To determine the interval containing the middle-most 48% of sample means, we need to find the z-scores that correspond to the lower and upper percentiles. The middle 48% corresponds to the range from the 26th percentile to the 74th percentile (100% - 48% = 52% / 2 = 26%).

Using a standard normal distribution table or a calculator, we can find the z-scores corresponding to these percentiles. The z-score for the 26th percentile is approximately -0.675 and the z-score for the 74th percentile is approximately 0.675.

Now, we can calculate the corresponding values for the sample means using the formula:

Sample Mean = Population Mean + (Z-Score) * (Standard Deviation / √Sample Size)

Lower Bound = 90 + (-0.675) * (20 / √35) ≈ 88.23

Upper Bound = 90 + (0.675) * (20 / √35) ≈ 91.77

Therefore, the interval containing the middle-most 48% of sample means is approximately [88.23, 91.77] (using interval notation).

The correct null hypothesis in the given situation is:

What is the null hypothesis?

Any variation between the selected attributes that you observe in a collection of data is thought to be the result of chance, according to the null hypothesis.

For instance, any discrepancy between the average profits in the data and zero is caused by chance if the expected earnings for the gambling game are actually equal to zero.

So, the population proportion serves as the parameter.

The American Academy of Periodontology found that 27% of US individuals admit to lying to their dentist about how frequently they floss their teeth.

So, the following is the null hypothesis:

H0: p = 0.27

Dr. Garcia, a periodontist, thinks that the percentage should be higher than 27% since he feels it is too low.

Consequently, the competing theory is:

H0: p > 0.27
