The management of White Industries is considering a new method of
assembling its golf cart. The present method requires 42.3 minutes, on
the average, to assemble a cart. The mean assembly time for a random
sample of 24 carts, using the new method, was 40.6 minutes, and the
standard deviation of the sample was 2.7 minutes. Using the .10 level
of significance, can we conclude that the assembly time using the new
method is faster?
