The​ 95% prediction interval for trouble shooting time with 8 hours of training was determined to be 12.822 to 19.261. What is the correct interpretation of this prediction​ interval?

Answer 1

We can be 95% sure that the true mean of the interval for trouble shooting time with 8 hours of training is between 12.822 and 19.261.

Explanation:

The​ 95% prediction interval for trouble shooting time with 8 hours of training was determined to be 12.822 to 19.261.
