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.

You are conducting a study to see if the accuracy rate for
fingerprint identification is significantly more than 0.66. You use
a significance level of α=0.001α=0.001.
H0:p=0.66H0:p=0.66
H1:p>0.66H1:p>0.66
You obtain a sample of size n=434n=434 in which there are 297
successes.

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 0.64. 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 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.
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 =
