Question

The SPSS figure shows the data and regression line for the 50 states in Table 3.6 relating x = percentage of single-parent families to y = annual murder rate (number of murders per 100,000 people in the population).
a. The lowest x value was for Utah and the highest was for Mississippi. Using the figure, approximate those x -values.
b. Using the regression equation stated above the figure, find the predicted murder rate at x = 0 . Why is it not sensible to make a prediction at x = 0 based on these data?
