A 95% confidence set for two or more coefficients is a set that contains:

You extract approximately 5,000 observations from the Current Population Survey (CPS) and estimate the following regression function: = 3.32 — 0.45Age, R2= 0.02, SER = 8.66         (1.00)   (0.04)where ahe is average hourly earnings, and Age is the individual’s age. Given the specification, your 95% confidence interval for the effect of changing age by 5 years is approximately:
