Step 1
Mean of x values (x̄) = (99 + 99 + 97 + 95 + 90 + 90 + 87 + 90 + 90) / 9 = 837 / 9 = 93 Mean of y values (ȳ) = (92 + 73 + 90 + 97 + 83 + 88 + 81 + 73 + 68) / 9 = 745 / 9 = 82.78 Show more…

The regression of Y on X is assumed as Y = α + βx + ε, answer the options using the following data. X 1 2 3 4 5 6 7 8 9 10 Y 4,7 4,5 4,5 4,2 4 3,9 3,5 3,3 3,4 3 A) Calculate α ve β. B) Calculate Y. C) Taking H0: β =0 and H1: β ≠0 and significance level of 0,05 test the regression. D) Calculate R2 and comment on the result.
