Consider the following model y = β0 + β1x + ∈, where y is the daily rate of return of a stock, and x is the daily rate of return of the stock market as a whole, measured by the daily rate of return of Standard & Poor's (S&P) 500 Composite Index. Using a random sample of n = 12 days from 1980, the least squares lines shown in the table below were obtained for four firms. The estimated standard error of 1 is shown to the right of each least squares prediction equation.
​
FirmEstimated Market ModelEstimated Standard Error of β1
Company Ay = .0010 + 1.40x​.03
Company By = .0005 - 1.21x​.06
Company Cy = .0010 + 1.62x1.34
Company Dy = .0013 + .76x​.15
​
For which of the three stocks, Companies B, C, or D, is there evidence (at α = .05) of a positive linear relationship between y and x?
◦ Company C only
◦ Companies B and D only
◦ Company D only
