1) 2) 3) 4) What are the crude pregnancy rates among high school girls in the two cities? For these data, what is the event being measured; what is the related variable; and which city has a relatively larger number in high risk categories? What would you expect to happen in you compute adjusted rates? Using a standard population which results from combining the populations of Cities A and B, use the direct method to arrive at adjusted rates for each city. What do you conclude about the rates of pregnancies among high school girls in Cities A and B
