When the R2 of a regression equation is very high, it indicates that all the coefficients are statistically significant. the intercept term has no economic meaning. a high proportion of the variation in the dependent variable can be accounted for by the variation in the independent variables. there is a good chance of serial correlation and so the equation must be discarded.
The owner of a movie theater company used multiple regression analysis to predict gross revenue (y) as a function of television advertising (x1) and newspaper advertising (x2). The estimated regression equation was ŷ = 83.7 + 2.23x1 + 1.60x2. The computer solution, based on a sample of eight weeks, provided SST = 25.4 and SSR = 23.445.

The proportion of the variability in the dependent variable that can be explained by the estimated multiple regression equation is (??) . Adjusting for the number of independent variables in the model, the proportion of the variability in the dependent variable that can be explained by the estimated multiple regression equation is (??).

A 95% confidence interval for the slope of a simple linear regression model is found to be (0.0046, 0.0252). This means that Select one: a. We are 95% confident the value of the predictor variable will increase by between 0.0046 and 0.0252 units. b. We are 95% confident that the average value of the response value lies between 0.0046 and 0.0252 c. We are 95% confident that the average value of response increases by between 0.0046 and 0.0252 units for every unit increase in the predictor. d.
