CRA CDs Inc. wants the mean lengths of the "cuts" on a CD to be 160 seconds (2 minutes and 40 seconds). This will allow the disk jockeys to have plenty of time for commercials within each 10-minute segment. Assume the distribution of the length of the cuts follows the normal distribution with a population standard deviation of 8 seconds. Suppose we select a sample of 15 cuts from various CDs sold by CRA CDs Inc. What percent of the sample means will be greater than 162 seconds? What percent of the sample means will be greater than 153 but less than 162 seconds?
