Question:

Suppose you estimate a regression of y against x and find that b = 1.3 and σ_b = .4 (population standard error of the regression, which is known).

(a) Construct a 90 % and a 99 % confidence interval for b.

(b) Now suppose σ_b is not known. How would this change the way you construct your confidence interval for b? Assume that 15 observations were used to estimate the regression.
