follow up question, which multiple choice is correct?

In a random sample of twelve cell phones, the mean full retail price was $455.00 and the standard deviation was $171.00. 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 p. Interpret the results. Identify the margin of error. 108.6 dollars (Round to one decimal place as needed.) Construct a 95% confidence interval for the population mean. (346.4 , 563.6 ) (Round to 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.) O A. 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. O B. of all random samples of twelve people from the population of cell phones will have a mean full retail price (in dollars) that is between the interval's endpoints. O C. It can be said that % of the population of cell phones have full retail prices (in dollars) that are between the interval's endpoints. O D. With % confidence, it can be said that the population mean full retail price of cell phones (in dollars) is between the interval's endpoints
