Question: In Example 9.4c, suppose we want an interval that we can be 95 percent certain will contain the height of a given male whose father

In Example 9.4c, suppose we want an interval that we can “be 95 percent certain” will contain the height of a given male whose father is 68 inches tall. A simple computation now yields the prediction interval Y (68) ∈ 67.568 ± 1.050 or, with 95 percent confidence, the person’s height will be between 66.518 and 68.618.
