The toylot company makes an electric train with a motor that it claims will draw an average of only 0.8 ampere (a) under a normal load. a sample of nine motors was tested, and it was found that the mean current was x = 1.34 a, with a sample standard deviation of s = 0.48 a. do the data indicate that the toylot claim of 0.8 a is too low?
what is the value of the sample test statistic? (round your answer to three decimal places.)find the p-value. (round your answer to four decimal places.)
