A hypothesis test is conducted with H0:p=0.61 and H1:p>0.61. A simple random sample of size n=75, there were 52 successes. Compute the test statistic. (Round to three decimal places.) Determine the P-value. (Round to four decimals places.)

After the political ad campaign, pollsters check the mayor's positives. They test the hypothesis that the ads produced no change against the alternative that the positives are now above 47% and find a P-value of 0.283. Which conclusion is appropriate? Explain. Choose the correct answer below. O A. There is a 28.3% chance that natural sampling variation could produce poll results at least as far above 47% as these if there is really no change in public opinion. There is a 28.3% chance that the poll they conducted is correct. O B. O C. There is a 71.7% chance that the ads worked. O D. There is a 28.3% chance that the ads worked.

Never Married People The percentage of males  18  years and older who have never married is  30.4 . For females the percentage is  23.6 . Looking at the records in a particular populous county, a random sample of  250  men showed that  73  had never married and  50  of  200  women had never married. At the  0.05  level of significance, is the proportion of men greater than the proportion of women? Use the  P -value method and let  p1  be the proportion of men.

Suppose the Humane Society claims that 30% of U.S. households own cats. You believe your community is different than the U.S. percentage. To test the claim, you take a simple random sample of 300 households and find that 37% own cats. Test at 5% significance.
