Confidence interval for a regression coefficient. In each of the following settings, give a 95% confidence interval for the coefficient of x1.

(a) n = 28, ˆy = 10.3 + 14.7x1 + 17.3x2, SEb1

= 7.4.

(b) n = 53, ˆy = 10.3 + 14.7x1 + 17.3x2, SEb1

= 7.4.

(c) n = 28, ˆy = 10.3 + 14.7x1 + 17.3x2 + 2.1x3, SEb1

= 7.4.

(d) n = 53, ˆy = 10.3 + 14.7x1 + 17.3x2 + 2.1x3, SEb1

= 7.4.
