The management of White Industries is considering a new method of assembling its golf carts. The present method requires an average of 42.3 minutes to assemble a cart. The mean assembly time for a random sample of 25 carts, using the new method, was 41.0 minutes. From historical information, the population standard deviation is known to be 2.7 minutes. Using an alpha value of .10, can we conclude that the assembly time using the new method is different than it was using the current method? The hypothesis statements for this problem are: H0: μ = 42.3 H1: μ ≠ 42.3
Use the p-Value Method. Note that if you do not use the p-Value method you will receive no credit for this problem.
