# Econometrics - Confidence Intervals watch

1. Can anyone help me find se (b2)? If I can calculate that I can do the rest of the problem. I wasn't given standard deviation or var (b2) so I have no idea how to derive it. FYI this is a calc-free class.
Here's the question:

Based on the data for years 1962-1977 for U.S., Dale Bails and Larry Peppers obtained the following demand function for automobiles:

Yhatt=5807+3.24x t
r^2=0.22
se= (1.634)
Where Y=retail sales of passenger cars (in thousands), and x equals the real disposable income (in billions of 1972 dollars)
Note: The se for b1 is not given.

a) establish a 95% confidence interval for B2
