Finding a Prediction Interval For someone with a foot length of 29.0 cm, identify the 95% prediction interval estimate of their height, and write a statement interpreting that interval.
Interpreting a Computer Display. In Exercises 9–12, refer to the display obtained by using the paired data consisting of foot lengths (cm) and heights (cm) of 40 people .
(Unlike the examples in this section, these exercises use foot lengths instead of shoe print lengths.) Along with the paired sample data, a foot length of 29.0 cm is used for predicting height.
