In a random sample of ten cell phones, the mean full retail price was $458.00 and the standard deviation was $220.00. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a
99% confidence interval for the population mean u. Interpret the results.
Identify the margin of error.
(Round to one decimal place as needed.)
