Access the data labeled Debt Payments from the text website and estimate Debt = β0 + β1 Income + ε , where Debt is the average debt payments for a household in a particular city (in $) and Income is the city's median income (in $1,000s).
a. Construct a 95% confidence interval for expected debt payments if income is $80,000 (remember that income is measured in $1,000s).
b. Construct a 95% prediction interval for debt payments if income is $80,000 (remember that income is measured in $1,000s).
