Problem 2

The notation z is the z-score such that the area under the standard normal curve to the right of z is _______ .

Step-by-Step Solution:

Step 1 of 5) The notation z is the z-score such that the area under the standard normal curve to the right of z is. Solution Figure 14 shows the correlation matrix from Minitab. The linear correlation between total cholesterol and age is 0.718. The linear correlation between total cholesterol and average daily consumption of saturated fat is 0.778. Because the linear correlation between average daily consumption and age, the two explanatory variables, is only 0.324, we are not concerned with multicollinearity. Use Technology to Find a Multiple Regression Equation When obtaining a multiple regression equation, perform the same diagnostic tests that we performed for the least-squares regression model with one explanatory variable. Always draw residual plots to verify that the model is appropriate.
