D Assume data were then collected for a fairly rural state and they found 70 eight-year olds diagnosed with ASD out of 2841 eight-year olds evaluated. Is there enough evidence to show that the proportion of children diagnosed with ASD in the fairly urban state is lower than the proportion in the fairly rural state? a.) Test at the 4% level b.) Compute a 96% confidence interval for the difference in proportions. Use the following steps for the hypothesis test. For the confidence interval you do not need to do all the steps since you did some of them already in hypothesis test. Part a.)
