Question

5. You are a manufacturer who wants to obtain a quality measure on a product, but the procedure to obtain the measure of how well the product works (Score 2) takes over an hour. There is an indirect approach, which uses a different product score (Score 1) in place of the actual quality measure. This approach takes only a minute but also is less precise. Use a stat > linear regression > fitted line plot in Minitab to see if Score 1 explains a significant amount of variance in Score 2. What is the p value? What is the R(sq)?
