6. The dataset RestaurantTips contains tips from a particular restaurant in New York. Use the dataset to find a multiple linear regression model to predict tips (y) based on bill size (a1 ) and number of guests (x2). Include the table of coefficients with their corresponding standard errors, t-stats, p-values, and the ANOVA output. 7. Use your regression model to estimate the tips for a $25 bill and 2 guests. 8. Which predictor variable is (i) the most significant in the model? (i) the least significant in the model? 9. Interpret the coefficient of determination in context of the problem. 10. Create a scatter plot of residuals versus fitted values
