Listed below are altitudes (thousands of feet) and outside air temperatures ("F) recorded during a flight. 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 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet). 31 Altitude Temperature a. Find the explained variation. 0 (Round to two decimal places as needed.) b. Find the unexplained variation. 0 (Round to five decimal places as needed.) c. Find the indicated prediction interval. °F
