If a population is known to be normally distributed with mue =74 and sigma =9, what will be the characteristics of the sampling distribution for x overbar based on a random sample of size 9 selected from the population?
mu Subscript x over bar = (Type an integer or a decimal.)
sigma Subscript x overbar = (Type an integer or a decimal.)
Describe the sampling distribution of the sample. Choose the correct answer below.
A. The sampling distribution is normally distributed because the population is normally distributed.
B. The sampling distribution is skewed right because the population is normally distributed and the sample size is less than 30.
C. The sampling distribution is skewed left because the population is normally distributed and the sample size is less than 30.
D. The sampling distribution is normally distributed by the Central Limit Theorem.
E. The sampling distribution cannot be described without actual data.

The heights of fully grown trees of a specific species are normally distributed, with a mean of 50.5 feet and a standard deviation of 6.00 feet. Random samples of size 17 are drawn from the population. Use the central limit theorem to find the mean and standard error of the sampling distribution. Then sketch a graph of the sampling distribution. The mean of the sampling distribution is mu Subscript x overbarequals nothing. The standard error of the sampling distribution is...
