Question: The manufacturer wants to change its sampling procedure so that they can estimate the confidence interval for the mean diameter of a particular gear given a specified amount of error.

Part 1: Complete the following table to show how many gears they would need to sampled for various error tolerance values ( m ) at various levels of confidence. Assume the population has a normal distribution with mean of 2.0 cm and standard deviation of 0.04 cm.

Part 2: Construct a well-designed, single graph of your results for Part a that shows how the number of samples required depends on both the confidence level and the level of error tolerance.
