In a random sample of eight cell phones, the mean full retail price was $403.50 and the standard deviation was $175.00. Assume the population is normally distributed and use the t-distribution to find the confidence interval for the population mean μ. Interpret the results. Identify the margin of error. (Round to one decimal place as needed.) Construct a 95% confidence interval for the population mean. (Round one decimal place as needed.) Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) OA. With % confidence, it can be said that the population mean full retail price of cell phones (in dollars) is between the interval's endpoints. OB. % of all random samples of eight people from the population of cell phones will have a mean full retail price (in dollars) that is between the interval's endpoints. OC. With % confidence, it can be said that most cell phones in the population have full retail prices (in dollars) that are between the interval's endpoints. OD. It can be said that % of the population of cell phones have full retail prices (in dollars) that are between the interval's endpoints.
