The following it a scatter plot of the percent of children under age 18 who are not in school or in the labor force versus the number of juvenile violent crime arrests for each of the 50 states. The least squares regression line has been drawn in on the plot. Given that a state had 6 percent not in school or labor, the predicted number of juvenile violent crime arrests for that state is close to 185. Close to 400. Close to 575. Impossible to calculate since the point isn\'t on the line. For the state with 8.5 percent not in school or labor, the residual is close to 200. Close to 200. Close to 400. Impossible to calculate since there is only one observation at x = 8.5. Removing the point for which x - 14.4 will change the slope. Change the intercept. Change the correlation. Cause all of the above.

Solution

a)

close to 400

b)

impossible to calculate at x=8.5

c)

change the slope
