In the past, when elementary school children in a large city were screened, 21% were found to have auditory defects. In a recent study of 100 children in the city who had been screened within the past month, 34 were found to have such defects. Do these data suggest a significant increase in the proportion of children having auditory defects? Test at a = 0.01. Round your answers to three decimal places, and round any interim calculations to four decimal places. What is the test statistic?
