Following is a regression equation.



y' = 20.62 + 0.24x



This information is also available: Se = 4.45, Σ
x = 280, Σ(x− x¯)2
= 1020, and 7 .


a. Estimate the value of y' when x = 46. (Round the final answer to 2 decimal places.)


y' =
31.66


b. Develop a 95% prediction interval for an individual value of y for x = 46. (Round the final answers to 2 decimal places.)
