answer with explanation

In a random sample of five mobile devices, the mean repair cost was $90.00 and the standard deviation was $12.50. Assume the population is normally distributed and use a t-distribution to find the margin of error and construct a 95% confidence interval for the population mean. Interpret the results. The 95% confidence interval for the population mean u is .) (Round to two decimal places as needed.)
