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 =
Given that,
This is the left tailed test .
P(z < -1.104) = 0.1348
P-value = 0.1348

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 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.
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 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.
