A foreign automobile manufacturer is spending hundreds of millions of dollars to construct a large manufacturing plant (about 70 acres under one roof) here in the United States. One of its objectives is to produce cars of high quality in the United States using U.S. workers. One part of the massive orientation program for new employees is to send about 20% of them to the home country for additional training. One measure of the worth of this additional training is whether the product quality is better on assembly lines where 20% of the employees have had the homeland orientation and have been able to share it with their fellow employees. Data from six assembly lines (three with the additional orientation) are shown here. Two different inspectors examined each of two cars chosen at random for defects from the assembly lines. Use these data to answer the following questions.
a. Suggest an appropriate dependent variable.
b. Write a model for this experimental situation and identify all terms.
c. Fill out the sources and degrees of freedom for an AOV table.
