Listed below are amounts of court income and salaries paid to the town justices for a certain town. All amounts are in thousands of dollars. Find the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. There is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. For the prediction interval, use a 99%confidence level with a court income of $800,000. Court Income $63 $410 $1556 $1123 $297 $252 $105 $159 $26 Justice Salary $25 $42 $92 $54 $47 $63 $25 $26 $20 a. Find the explained variation. ______________ (Round to three decimal places as needed.) b. Find the unexplained variation. _______________ (Round to three decimal places as needed.) c. Find the indicated prediction interval. $ _____________ < y < $ ____________ (Round to four decimal places as needed.)
