You are conducting a study to see if the probability of catching the flu this year is significantly less than 0.13. You use a significance level of α=0.002 H0:p=0.13 H1:p<0.13 You obtain a sample of size n=749 in which there are 84 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 = The p-value...
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly less than 0.64. Thus you are performing a left-tailed test. Your sample data produce the test statistic z=−1.104. Find the p-value accurate to 4 decimal places. p-value =
You are conducting a study to see if the probability of catching the flu this year is significantly different from 0.39. You use a significance level of α=0.02 α=0.02 . H0:p=0.39 H0:p=0.39 H1:p≠0.39 H1:p≠0.39 You obtain a sample of size n=427 n=427 in which there are 190 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.)...
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.16. Thus you are performing a two-tailed test. Your sample data produce the test statistic z=−3.214. Find the p-value accurate to 4 decimal places. p-value =
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly less than 0.79. With H :P < 0.79 you obtain a test statistic of z = - 3.061. 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 accuracy rate for fingerprint identification is significantly different from 0.66. Thus you are performing a two-tailed test. Your sample data produce the test statistic z= −1.776. 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 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 different from 0.84. Thus you are performing a two-tailed test. Your sample data produce the test statistic z=2.029 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 =
