Hono Golf is a manufacturer of golf products in Taiwan and China. One of the golf accessories it produces at its plant in Tainan Hsing, Taiwan, is plastic golf tees. The injector molder produces golf tees that are designed to have an average height of 66 mm. To determine if this specification is met, random samples are taken from the production floor. One sample is contained in the file labeled THeight.

a. Determine if the process is not producing the tees to specification. Use a significance level of 0.01.

b. If the hypothesis test determines the specification is not being met, the production process will be shut down while causes and remedies are determined.

At times this occurs even though the process is functioning to specification. What type of statistical error would this be?
