The diameter of a brand of tennis balls is approximately normally distributed, with a mean of 2.58 inches and a standard deviation of 0.06 inch. A random sample of 11 tennis balls is selected. Complete parts (a) through (d) below. ()B. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 11 will not be approximately normal O C. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 11 cannot be found O D. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution of samples of size 11 will be the uniform distribution. b. What is the probability that the sample mean is less than 2.55 inches? P(X
