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 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 catching the flu this year is significantly less than p = 0.47. Thus you are performing a left-tailed test. Your sample data produce the test statistic z = -1.969. Find the p-value accurate to 4 decimal places.
please help! see all pics! 5. (1 pts) 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 0.59. Thus you are performing a test statistic z -1.835. Find the p-value accurate to 4 decimal places. Label the standard normal curve and shade the appropriate area. -tailed test. Your sample data produce the p-value= 6. (6 pts) Test the claim that the proportion of people...
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 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 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 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 79%. With H1 : p ≠ 79% you obtain a test statistic of z=2.321. Find the p-value accurate to 4 decimal places.
