Question
Sampling distributions asked 2020-11-11
Explain how to use the sampling distributions of A and B to decide which is the best estimator of $$\alpha$$.

## Answers (1) 2020-11-12
It is given that the sample statistic B is an unbiased estimator of the population parameter $$\alpha$$.
Here, A and B are unbiased estimators of $$\alpha$$. The standard deviations of A and B should be compared for deciding the best estimator of $$\alpha$$. The best estimator of $$\alpha$$ is the statistic that has the smaller standard deviation.

Which of the following is true about the sampling distribution of means?
A. Shape of the sampling distribution of means is always the same shape as the population distribution, no matter what the sample size is.
B. Sampling distributions of means are always nearly normal.

Explain the meaning of assertion that A is an unbiased estimator of $$\alpha$$ asked 2021-02-19
The distribution of height for a certain population of women is approximately normal with mean 65 inches and standard deviation 3.5 inches. Consider two different random samples taken from the population, one of size 5 and one of size 85.
Which of the following is true about the sampling distributions of the sample mean for the two sample sizes?
Both distributions are approximately normal with mean 65 and standard deviation 3.5.
A
Both distributions are approximately normal. The mean and standard deviation for size 5 are both less than the mean and standard deviation for size 85.
B
Both distributions are approximately normal with the same mean. The standard deviation for size 5 is greater than that for size 85.
C
Only the distribution for size 85 is approximately normal. Both distributions have mean 65 and standard deviation 3.5.
D
Only the distribution for size 85 is approximately normal. The mean and standard deviation for size 5 are both less than the mean and standard deviation for size 85.
