Using the heights and weights described in Exercise I a heig

Using the heights and weights described in Exercise I, a height of 180 cm is used to find that the predicted weight us 88.0 kg, and the 95% prediction interval is displayed by Minitab as (50.7, 123.0). Write a statement that inter Interpreting the Coefficient of Determination. In Exercises 5-8, use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage to the total variation that can be explained by the linear relationship between the two variables from the Appendix B data sets. toterpreting a Computer Display. In Exercises 9-12, refer to the Minitab display Stained by using the paired data consisting of foot lengths (cm) and heights (cm) of the 40people listed in Data Set 2 of Appendix B. (Unlike the examples in this section, these me foot lengths instead of shoe print lengths.) Along with the paired sample Miniusb was also given afoot length of29.0 cm to be used for predicting height,.

Solution

5) r^2 = 0.8710 = 87.10%

percentage of variation that is explained by the model

6) r^2 = 0.927 = 92.7%

7) r^2 = 0.6288 = 62.88%

8) r^2 = 0.564 = 56.4%
