- Obtain and interpret a 95% confidence interval for β1β1. Assume the assumptions can be verified
- For the fitted regression model, SSR = 132306 and SSE = 54207, calculate and interpret the coefficient of determination.

Transcribed Image Text:A random sample of 90 weightlifters was collected from the A class of the 2019 European Championships held in Batumi, Georgia. We are
interested in determining if the body weight of the athlete (in kilograms) is a reasonable linear predictor for the total amount the athlete can lift
(also in kilograms). Consider the following summary statistics: = 90.44467, Ser = 48955.71, Sry
Syy = 186513.6, and s, = 24.82.
= 80480.74, y = 335.2222,
d. Obtain and interpret a 95% confidence interval for B1B1. Assume the assumptions can be
verified
e. For the fitted regression model, SSR = 132306 and SSE = 54207, calculate and interpret
the coefficient of determination.
