Should the multiple regression equation be used for predicting the LDL cholesterol level based on weight and diastolic blood pressure? Why or why not?
We want to consider the correlation between LDL cholesterol and the predictor variables of weight (W7) and systolic blood pressure (SYS) for females. Refer to the Minitab display and answer the given questions or identify the indicated items. The Minitab display is based on the measured values of LDL cholesterol weight, and systolic blood pressure amounts for the sample of 40 females from Data Set 1 of Appendix B.
