The sampling distribution of means is: A list of all members of the population you are studying. Also called the standard error of the mean. A set of numbers representing all of the possible sample means on a variable you could draw from a given population and a given sample size. A list of all members of the sample that you draw. 1 points Question 2 The standard deviation of the sampling distribution of means is called the: Margin of...

Which of the following is true about the sampling distribution of means? Shape of the sampling distribution of means is always the same shape as the population distribution, no matter what the sample size is. Sampling distribution of the mean is always right skewed since means cannot be smaller than 0. Sampling distributions of means are always nearly normal. Sampling distributions of means get closer to normality as the sample size increases.

Which of the following statements is CORRECT about the sampling distribution of the sample mean: A. The standard error of the sample mean is a measure of the frequency among repeated samples. B. The standard error of the sample mean will decrease as the sample size increases. C. The standard error of the sample is completely unrelated to the sample size. D. The standard error of the sample mean will increase as the sample size increases.
