Toys: Electric Trains 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 51.4A, with a sample standard deviation of s 5 0.41A. Do the data indicate that the Toylot claim of 0.8 A is too low? (Use a 1%

level of significance.)
