The management of KSmall Industries is considering a new method of assembling a computer. The current assembling method requires a mean time of 86 minutes with a standard deviation of 7.4 minutes. Using the new method, the mean assembly time for a random sample of 24 computers was 71 minutes. Required: a. Using the 0.10 level of significance, can we conclude that the assembly time using the new method is faster? Reject Ho The mean assembly time is b. What is the probability of a Type Il error? Note: Round "Critical values" to 2 decimal places and round your final answer to 4 decimal places. Probability of Type II error less than 86 minutes. 0.0000
