Using the data below: (i) Find the regression line (show your manual calculation, and do not use Excel ) (5 Points), {ii} compute the standard error of the estimate {5 Points}, {iii} calculate the estimated standard deviation of hi (5 Points}, and (iv) use the t-test to test if there is a linear relationship exist between x and y. [5 Points} Use at = .05. O a) (i) y=6+2.03x (ii) 10.033 (iii) 0.0043 (iv) There is a linear relationship exist between x and y. O b) (i) y=4+2.03x (ii) 1.033 (iii) 0.443 (iv) There is a no linear relationship exist between x and y. O c) None of the answers are correct
