Do pregnant women give birth the week of their due date? A study claims that 21% of the population of all pregnant women actually gave birth the week oftheir due date. You are a researcher who wants to test this claim, so you will select a random sample of 60 women who have recently given birth.Follow the steps below to construct a 95% confidence interval for the population proportion of all pregnant women who gave birth the week of their due date.Then state whether the confidence interval you construct contradicts the study's claim. (If necessary, consult a list of formulas.)(a) Click on "Take Sample" to see the results from the random sample.NumberProportionTake SampleGave birth the week of due date210.35Did not give birth the week of due date390.65
