The management of KSmall Industries is considering a new method of assembling a computer. The current assembling method requires a mean time of 80 minutes with a standard deviation of 5.9 minutes. Using the new method, the mean assembly time for a random sample of 24 computers was 68 minutes.
Required:
Using the 0.10 level of significance, can we conclude that the assembly time using the new method is faster? What is the probability of a Type II error?
