Question 4 A magazine publishes restaurant ratings for various locations around the world. The magazine rates the restaurants for food, decor, service, and the cost per person. Given below are the output for predicting cost (RM per person) using the summated ratings for a sample of 25 hotels in a major city. Answer the questions based on the statistical output. Model Summary Model R R Square Adjusted R Std. Error of the Square Estimate 0.778 0.605 0.587 8.601 a. Predictors: (Constant), Rating b.
