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 25 women who have recently given birth. Follow the steps below to construct a 90% 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. Number Proportion Take Sample Gave birth the week of due date 13 0.52 Did not give birth the week of due date 12 0.48 Enter the values of the sample size, the point estimate of the population proportion, and the critical value you need for your 90% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute". Sample size: Point estimate: 0 Critical value: 0 Compute Standard error: Margin of error: Confidence level Critical value 99% F0.0052.576 90% confidence interval: 95% F0.025 1.960 90% F0.050 1.645 (b) Based on your sample, enter the lower and upper limits to graph the 90% confidence interval for the population proportion of all pregnant women who gave birth the week of their due date. 0.000 0.000 90% confidence interval: 1.000 1.000
