Solve this Central Limit Theorem problem. Round the standard error to the nearest thousandth and the z-score to the nearest hundredth whenever necessary. An analyst at a cell phone company finds that for those who exceed the minutes included in their basic contract, the extra time used has a mean of u = 22 minutes and a standard deviation of o = 9 minutes. Beatrice finds a SRS of 60 customers who used extra minutes. Use the CLT to determine p(x s 24.5 minutes).
