In a random sample of 7 cell​ phones, the mean full retail price was ​$512.60 and the standard deviation was ​$186.00. Further research suggests that the population mean is ​$431.12. Does the​ t-value for the original sample fall between −t0.99 and t0.99​? Assume that the population of full retail prices for cell phones is normally distributed.   The​ t-value of t=? Does or does it not fall between −t0.99 and t0.99 because t0.99 =?
