In seeking а free аgent NFL running bаck, a general manager is lооking fоr a player with a high mean for yards gained per carry and a small standard deviation. Suppose the GM wishes to compare the mean yards gained per carry for two free agents based on independent random samples of their yards gained per carry. Data from last year's pro football season indicate that σ1 and σ2 are both equal to approximately 5 yards. If the GM wants to estimate the difference in means for yards gained per carry by the two running backs correct to within 1 yard with a confidence level of 0.90, how many carries would have to be observed for each of the two players? Assume equal sample sizes.
