\\._/ In a random sample of seven cell phones. the mean full retail price was $435.00 and the standard deviation was $225.00. Assume the population is normally distributed and use the tdistribution to nd the margin of error and construct a 99% condence interval for the population mean p. Interpret the results. Identify the margin of error. 316.7 dollars (Round to one decimal place as needed.) Construct a 99% condence interval for the population mean. [1133,1511] [Round to one decimal place as needed.) Interpret the results. Select the correct choice below and ll in the answer box to complete your choice. {Type an integer or a decimal. Do not round.) 0 A- With 13% confidence, it can be said that most cell phones in the population have full retail prices (in dollars) that are between the intervals endpoints. O 3- With [I96 confidencer it can be said that the population mean full retail price of cell phones (in dollars) is between the interval's endpoints. O c- It can be said that 13% of the population of cell phones have full retail prices [in dollars) that are between the interval's endpoints. O D- '36 of all random samples of seven people from the population of cell phones will have a mean full retail price (in dollars) that is between the intervals endpoints
