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 85 damps, the
mean time to complete this step was 50.5 seconds. Assume that the population standard deviation is 0 - 12 seconds. Round the
critical value to no less than three decimal places.
Part: 0/2
Part 1 of 2
