Trials in an experiment with a polygraph include 97 results that include 22 cases of wrong results and 75 cases of correct results. Use a 0.01 significance level to test the claim that such polygraph results are correct less than 80% of the time. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial...

Identify the land atemative hypotheses. Choose the correct answer below. OA...
For each question Identify the test statistic(round two decimal places) Identify the P-value(round three decimal places) Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6014 patients treated with this drug, 159 developed the adverse reaction of nausea. Use a 0.05 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction? Identify the null and alternative hypotheses for this test....
In a program designed to help patients stop smoking, 236 patients were given sustained care, and 84.3% of them were no longer smoking after one month. Use a 0.05 significance level to test the claim that 80% of patients stop smoking when given sustained care. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho:p*0.8 H: p=0.8 OB. Ho: P = 0.8 H:p<0.8 @ C. Ho: p = 0.8 H:p*0.8 OD. Ho: p=0.8...

The test statistic of z= 1.27 is obtained when testing the claim that p>0.7. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.05, should we reject H, or should we fail to reject H,? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. This is a right-tailed test. b....
A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study, 407 babies were born, and 216 of them were girls. Use the sample data with a 0.01 significance level to test the claim that with this method, the probability of a baby being a girl is greater than 0.5. Use this information to answer the following questions. a. Which of the following is the hypothesis test to be conducted? O A. Ho:...
