claims that 38 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 Take Sample Sample size 0 Point estimate 0 Critical value 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 Compute Gave birth the week of due date Did not give birth the week of due date 0 000 H 0 000 Standard error Margin of error 90 confidence interval Number Proportion 18 22 90 confidence interval 0 500 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 date O No the confidence interval does not contradict the claim The proportion 0 38 from the study is inside the 90 confidence interval 0 45 O No the confidence interval does not contradict the claim The proportion 0 38 from the study is outside the 90 confidence interval 0 55 Enter the values for the lower and upper limits on the graph to show your confidence interval For the point enter the claim 0 38 from the study O Yes the confidence interval contradicts the claim The proportion 0 38 from the study is inside the 90 confidence interval O Yes the confidence interval contradicts the claim The proportion 0 38 from the study is outside the 90 confidence interval X values 20 005 2 576 20 010 2 326 X 20 025 1 960 20 050 1 645 20 100 1 282 c Does the 90 confidence interval you constructed contradict the claim from the study Choose the best answer from the choices below S 1 000 5 S 1 000 2 999 Aa M
