QUESTIONS 1. An analyst looking at the fitted line plot proposed a linear relationship between service time and the number of components replaced. Interpret the meaning of the coefficients. 2. Using the analysis of variance table, conduct the F test. Compute the standard error of estimate and the R 2. Interpret your results. 3. Using the residual; plot, examine the residuals to see if the fitted model is adequate. Do you think that the fitted model adequately explains the service times? Give reasons
