Explanation / Answer

a) y^ = 1.82162 + 0.18467 *x1 + 0.00012 *x2

b) b0 - option C) is correct

b1 - option C) is correct

b2 - option C) is correct

c) 98 % confidence interval

t = 2.364

(0.18467 - 2.364 *0.03128) , ( 0.18467 + 2.364 *0.03128)

=(0.1107240,0.2586159)

correct option is A)

d) similarly 98 % confidence interval for b2 is

(0.00012 - 2.364 * 0.00003),(0.00012 +2.364 * 0.00003)

=(0.00004908,0.00019092)
