CI for the Mean Response at a Specified x ❚ A confidence interval for the mean response is: )% 1 ( 100 α Prediction Interval for a Single Response at a Specified x ❚ A prediction interval for a future response is: )% 1 ( 100 α Example (radiation): ❚ Give a 95% confidence interval for the mean response when the radiation is 24 picocuries/L ❚ Give a 95% prediction interval for the a single response when the radiation is 24 picocuries/L Example (radiation):...
