Dependent Variable: laptop sales These tables provide the output from a multiple regression analysis looking at the impact of number of internet acs and product attractiveness on online laptop sales. Does this model result in significantly better predictions than those based solely on the mean? How do you know? No, because the p-value associated with the F statistic is not less than .05. Yes, because the p-value associated with the t statistic is not less than .05. Yes, because the p-value associated with the F statistic is less than .05. No, because the R-square value is not greater than .50.
