Consider the linear regression model Y; = Bo + B1 X; + Ui for each i =1,...,n, where Y; represents the average test score of class i and X; represents thesize of class i. Which one of the following is true if the sample covariance between average test score and class size is -0.25?а.There is no correlation between Y;, X;b. The variance of X; is negativeС.The OLS estimate of B1 is negatived. The values of X1, ..., Xn are on average smaller than the values of Y1, . .. , Yn

Consider a regression analysis with n = 47 and three potential independent variables. Suppose that one of the independent variables has a correlation of 0.95 with the dependent variable. Does this imply that this independent variable will have a very large Student’s t statistic in the regression analysis with all three predictor variables?
4. A study was conducted to investigate the relationship between the size of a house (in square feet) and the selling price of a house (in dollars). The response variable is price in dollars, and we want to study if the covariate of the square footage helps explain the response.
