Suppose that variables x and y satisfy the assumptions for r
     Suppose that variables x and y satisfy the assumptions for regression inferences. For samples of size n, each with the same values for the predictor variable, what is the distribution of the slope beta_1, of the sample regression line?  Select one:  t-distribution with mean beta_1 and standard deviation sigma/t-distribution with mean beta_1 and standard deviation s_e  Normal with mean and standard deviation s_e  Normal with mean beta_1 and standard deviation sigma/squareroot 5_xx
