Question: Solve the following. a. Calculate a 95% confidence interval for 1 . b. .Find a test statistic and p-value for testing H 0 :

 Solve the following.

n = 500, x=-0.303, y = 1.476, sx Bo=1.896, 31 = 1.102,


a. Calculate a 95% confidence interval for β 1 .

b. .Find a test statistic and p-value for testing H 0 : β 1 = 0 vs. H a : β 1 > 0.

c. Calculate a 95% confidence interval for µ Y |X when x = 4.

d. Calculate a 95% prediction interval for Y when x = 2.



n = 500, x=-0.303, y = 1.476, sx Bo=1.896, 31 = 1.102, sy|x 2.279, Sy 1.868, so = 0.265, s = 0.431 = = = 3.280
