Use the 5 or 6 steps hypothesis testing for the following question (question 3 and 4)
3.. 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 64 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. Using the 0.10 level of significance, can we conclude that the assembly time using the new method is faster? Estimate the p-value. Show all five or 6 steps you use.
Is this a right-tail, left-tail or two-tail test?
