Efficiency experts study the processes used to manufacture items in order to make them as efficient as possible.

Efficient manufacturing: Efficiency experts study the processes used to manufacture items in order to make them as efficient as possible. One of the steps used to manufacture a metal clamp involves the drilling of three holes. In a sample of 75 clamps, the mean time to complete this step was 41.4 seconds. Assume that the population standard deviation is =σ 12 seconds. Round the critical value to no less than three decimal places.
