A survey of 920 preterm births before 28 month gestation was carried out in urban hospital and showed that 200 were breech presentations. Hypothesis is to be tested at 1% level of significance that for preterm births occurring before 28 months gestation, proportion of breech presentations is 0.20 against that it is more. For this test, determine the (a) the critical value for this test (b) the p-value for this test (c) determine the decision about the null hypothesis?
