Assume that the sample is a simple random sample obtained from a normally distributed population of flight delays at an airport. Use the table below to find the minimum sample size needed to be 99% confident that the sample standard deviation is within 50% of the population standard deviation. A histogram of a sample of those arrival delays suggests that the distribution is skewed, not normal. How does the distribution affect the sample size? The minimum sample size needed is Is this sample size practical? A.No, because the sample size should be as small possible for most applications B.Yes, because the sample size should be as large as possible for most applications. C.No, because the sample size is excessively large to be practical for most applications. D.Yes, because the sample size is small enough to be practical for most applications
