In a random sample of twelve cell phones, the mean full retail price was $595.50 and the standard deviation was $218.00. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 95% confidence interval for the population mean μ. Interpret the results. Identify the margin of error. (Round to one decimal place as needed.)
