The diameter of a brand of tennis balls is approximately normaliy distributed, with a mean of 2.68 inches and a standard deviation 010.05 inch. A random sample of 11 tennis balls is selected. Complete parts (a) through (d) below. (E) B. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples oi size 11 will be the uniform distribution. C. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 11 will not be approximately normal. 9" D. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 11 mil also be approximately normal. [1. What is the probability that the sample mean is less than 2.67 inches? P()
