Do pregnant women give birth the week of their due date? A study claims that 33% of the population of all pregnant women actually gave birth the week of their due date. You are a researcher who wants to test this claim, so you will select a random sample of so women who have recently given birth. Follow the steps below to construct a 99% 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.)

Transcribed Image Text:Do pregnant women give birth the week of their due date? A study
claims that 33% of the population of all pregnant women actually gave
birth the week of their due date. You are a researcher who wants to test
this claim, so you will select a random sample of so women who have
recently given birth.
Follow the steps below to construct a 99% 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.)
