In a random sample of 9 cellphones, the mean full retail price was $514.60 and the standard deviation was $179.00. Further research suggests that the population mean is $427.78. Does thet-value for the original sample fall between t0.95 and t0.95? Assume that the population of full retail prices for cell phones is normally distributed.

Thet-value of t=

nothing

does not

does

fall between t0.95 and t0.95 because t0.95=

(Round to two decimal places asneeded.)
