Problem 831

Constructing a confidence interval to test a claim about a population...
Do pregnant women give birth the week of their due date? A study claims that $20 \%$ 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 40 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. 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. \begin{tabular}{|l|l|c|c|} \hline Take Sample & Gave birth the week of due date & 14 & 0.35 \\ \hline & Did not give birth the week of due date & 26 & 0.65 \\ \hline \end{tabular}
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". \begin{tabular}{|l|l|} \hline \begin{tabular}{l} Sample size: \\ 40 \end{tabular} & Standard error: \\ \hline \begin{tabular}{l} Point estimate: \\ $\square$ \end{tabular} \\ \hline \begin{tabular}{l} Critical value: \\ 1.645 \end{tabular} & \\ \hline Compute \end{tabular} \begin{tabular}{|l|} \hline Critical values \\ \hline $z_{0.005}=2.576$ \\ \hline $z_{0.010}=2.326$ \\ \hline $z_{0.025}=1.960$ \\ \hline $z_{0.050}=1.645$ \\ \hline $z_{0.100}=1.282$ \\ \hline \end{tabular} (b) Based on your sample, graph the $90 \%$ confidence interval for the population proportion of all pregnant women who gave birth the week of their due
