I need help with part c of this question.

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). Altitude 2 12 16 25 27 31 32 Temperature 59 35 26 - 34 - 41 - 59 a. Find the explained variation. 10821.36 (Round to two decimal places as needed.) b. Find the unexplained variation. 855.49478 (Round to five decimal places as needed.) c. Find the indicated prediction interval. OF
