Chapter 10.2, Problem 11E
For Exercises 11 through 27, use the same data as for the corresponding exercises in Section 10–1. For each exercise, find the equation of the regression line and find the y′ value for the specified x value. Remember that no regression should be done when r is not significant.
11. Crimes The number of murders and robberies per 100,000 population for a random selection of states are shown.
Find y′ when x = 4.5 murders.
