The diameter of a brand of tennis balls is approximately normally distributed, with a mean of 2.59 inches and a standard deviation of 0.05 inch. A random sample of 11 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 11 cannot be found. B. Because the population diameter of tennis balls is approximately norrnaliy distributed, the sampling distribution of samples of size 11 will not be approximately normal. C. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 11 will be the uniform distribution. 3 D. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 11 will also be approximately normal. b. What is the probability that the sample mean is less than 2.58 inches? P() 2.200) = (Round to four decimal places as needed.) If a population is known to be normally distributed with p = 88 and 0' = 28, what will be the characteristics of the sampling distribution for R based on a random sample of size 16 selected from the population? p; = (Type an integer or a decimal.)
