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 61 clamps, the mean time to finish the step was 51.7 seconds. Assume that the population standard deviation is 8 seconds. What is the lower bound of the 98% confidence interval?
