Complete parts (a) through (d). ' 1,2.4,7,8.1o a (5) Assuming that you sample without replacement, select all possible samples of n = 2 and construct the sampling distribution of the mean. Compute the mean of all the sample means and compute the population mean. Are they equal? What is this property called? Construct the sampling distribution of the mean.

A random sample of 10 tennis balls is selected. Complete parts (a) through (d) below. a. What is the sampling distribution of the mean? A. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 10 will not be approximately normal. B. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 10 cannot be found. C. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 10 will also be approximately normal. D. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 10 will be the uniform distribution. b. What is the probability that the sample mean is less than 2.58 inches? P(X
