You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 0.86. Thus you are performing a two-tailed test. Your sample data produce the test statistic z = − 1.725 . Find the p-value accurate to 4 decimal places. p-value =
You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly more than 0.1. With H1 : p > 0.1 you obtain a test statistic of z = 3.073 . Use a normal distribution calculator and the test statistic to find the P-value accurate to 4 decimal places. It may be left-tailed, right-tailed, or 2-tailed. P-value =
You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 62%. With Ha : p ≠≠ 62% you obtain a test statistic of z=3.233. Find the p-value accurate to 4 decimal places. p
You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 0.17. You use a significance level of α=0.02. H0:p=0.17 H1:p≠0.17 You obtain a sample of size n=428 in which there are 56 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal...
You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly more than 84%. With Ha : p > > 84% you obtain a test statistic of z = 2.321 z=2.321 . Find the p-value accurate to 4 decimal places. p-value =
You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly different from 0.27. Thus you are performing a two-tailed test. Your sample data produce the test statistic z=2.887z=2.887. Find the p-value accurate to 4 decimal places.
You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly more than 0.67. You use a significance level of α=0.005α=0.005. H0:p=0.67H0:p=0.67 H1:p>0.67H1:p>0.67 You obtain a sample of size n=205n=205 in which there are 148 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = Incorrect What is the p-value for this sample? (Report answer accurate to four decimal places.)...
You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly different from 79%. With H1 : p ≠ 79% you obtain a test statistic of z=2.321. Find the p-value accurate to 4 decimal places.
You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly different from 48%. With H1 : p ≠≠ 48% you obtain a test statistic of z=−2.427z=-2.427. Find the p-value accurate to 4 decimal places. p-value =
You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly different from 0.23. You use a significance level of α=0.02. H0:p=0.23 H1:p≠0.23 You obtain a sample of size n=371 in which there are 108 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value =
