n a random sample of 9 cell phones, the mean full retail price was $523.90 and the standard deviation was $189.00 Further research suggests that the population mean is $432.24 Does the t-value for the original sample fall between −t 0.95 and t 0.95? Assume that the population of full retail prices for cell phones is normally distributed.
