The proportion of 200 children age 19-35 months from families in poverty who had inadequate polio vaccinations was found to be .21 in community A. Community B, which has a special program in place to increase vaccination of children from families in poverty, measured their vaccination proportion and found it to be. 12 among 150 children. Test the null hypothesis of equal proportions in the two communities using a = .05. Also compute a 95% confidence limit for the difference in the two proportions. Contrast what statements can be made from the test and the confidence limits
