Answer the following multiple choice questions 13-18 using the information below:Most supermarkets use scanners at the checkout counters. The data collected this way can be used to evaluate the effect of price and the store’s promotional activities on the sales of any product.

The objective is to develop a regression model of sales on the available predictors.As a preliminary analysis, a simple linear regression model was fitted.The fitted regression equation was: sales = 2259 – 1418 price.The ANOVA F test p-value was .000, and R²= 0.597
