True or False: Given the necessary assumption: E(u|X) = 0, β ̂ is a random variable with a distribution centered at 0. Given the necessary assumption: E(u|X) =0, β ̂ is a random variable with a distribution centered at β. Adding more independent variables to a model will only increase R2 if they provide meaningful variation. Adj R2 measures the proportion of the variation in the dependent variable that has been explained by the variation in the independent variable. If...

If re.5 between Ads and Sales. In the model Sales- 268 + 7.37 Ads, then Ads explains 50 percent of the variation in Sales True False In the linear regression between Ads and Sales, the p-value of the slope estimate is.042 which is less than a.05; therefore the linear relationship between Ads and Sales is not statistically significant True False
