2, The diameter of a brand of tennis balls is approximately normally distributed, with a mean 01 2.55 inches and a standard deviation of 0.06 inch. A random sample of 11 tennis balls is selected. Complete pans (a) through (d) below. a. What is the sampling distribution of the mean? 0 A. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution 01 samples 01 size 11 will not be approximately normal. 0 B. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution 01 samples 01 size 11 will also be approximately normal. 0 c. Because the population diameter of tennis balls is approximately normally distributed. the sampling distribution 01 samples 01 size 11 will be the unitorm distribution. 0 D. Because the population diameter of tennis balls is approximately normally distributed, the sampling distribution 01 samples 01 size 11 cannot be found. b. What is the probability that the sample mean is less than 2.52 inches? P()_(
