*11. Refer to Case Study 10.2, in which regression equations are given for males and females relating ideal weight to actual weight. The equations are Women: ideal  43.9  0.6 actual Men: ideal  52.5  0.7 actual

*a. Predict the ideal weight for a man who weighs 150 pounds and for a woman who weighs 150 pounds. Compare the results.

b. Does the intercept of 43.9 have a logical physical interpretation in the context of this example? Explain.

c. Does the slope of 0.6 have a logical interpretation in the context of this example?

Explain.

d. Outliers in scatterplots may be within the range of values for each variable individually but lie outside the general pattern when the variables are examined in combination. A few points in Figures 10.7 and 10.8 could be considered as outliers. In the context of this example, explain the characteristics of someone who appears as an outlier.
