The National Restaurant Association randomly selected 20 restaurants in a major metropolitan area and asked patrons to tell them about their experience. Each score below represents the percentage of respondends who rated a restaurant as either "excellent" or "very good" on several criteria including "Quality of Entrée", "Atmosphere", and "Quality/Speed of Service". An overall score was also used to ran the restuarants evaluated. The data is as follows: Restaurant Overall Entrée Quality Atmosphere Service 1 94.4 94.6 90.9 97.8 2 93.0 96.7 84.2 96.7 92.9 100.0 100.0 88.5

A. Determine the estimated regression equation that can be used to predict the overall score given the scores for Entrée Quality, Atmosphere, and
Quality/Speed of Service. What is the R score for that regression equation ?
B. Use the Ftest to determne the overall significance of the relationship. What is your conclusion at a 0.05 level of confidence ?
C. Use the t-test to determine the significance of each independent variable. What is your conclusion at the 0.05 level of significance?
D. Remove any independent variable that is not significant from your estimated regression equation. What is your recommended estimated regression
equation? What is the R value for that equation?
