Do pregnant women give birth the week of their due date? You are a researcher who wants to estimate the population proportion of all pregnant women who gave birth the week of their due date, so you will select a random sample of 80 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. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results from the random sample. (b) Take Sample Sample size: 0 Point estimate: Critical value: Compute 0.000 Gave birth the week of due date Enter the values of the sample size, the point estimate of the population proportion, and the critical value you need for your 99% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute". 0.000 Did not give birth the week of due date Standard error: Margin of error: 99% confidence interval: Number Proportion 28 52 99% confidence interval: Confidence level 99% 95% 0.35 90% 0.65 Based on your sample, enter the lower and upper limits to graph the 99% confidence interval for the population proportion of all pregnant women who gave birth the week of their due date.
