The LEGO Group, an international company, makes the LEGO blocks that many of us have played with as kids. Many of its products require that the production process performs according to specifications. One of the products is Little People. The neck diameter of each of the Little People must be 0.5 inches so that it can be attached to the head properly. LEGO is interested in testing to see whether this process is performing according to specifications. If it is not functioning correctly, the LEGO Group will shut down the manufacturing process to fix the Little People machine. Discuss the following: a. What is a Type I error for this situation? What are the consequences of such an error?
b. What is a Type II error for this situation? What are the implications of such an error?
c. In this example, which error--a Type I or a Type II--is more serious?
