The owner of a large equipment rental company wants to make a rather quick estimate of the mean number of days a piece of equipment is rented out per person per time.
The
owner decides to take a random sample of 16 invoices and finds that the sample mean
rental time is 2.54 days and the sample standard deviation is 2 days. A 95 o confidence
interval to estimate the population mean number of days for the rental is going to be
calculated. What is the upper bound (the larger number in the interval estimate) for the
95% confidence interval? (Round your final answer to 2 decimal places)
