Question

The file P02_16.xlsx contains the number of arrivals at a turnpike tollbooth for each of four 5-minute intervals for each of 256 days. For this problem, assume that each column, such as arrivals from 8:00 AM to 8:05 AM, is a random sample of all arrivals from the corresponding hour of the day, such as 8:00 AM to 9:00 AM. Find a 95% confidence interval for the mean number of arrivals during each corresponding hour of the day, that is, one for 8:00 AM to 9:00 AM, one for 9:00 AM to 10:00 AM, and so on.
