P VALUE FOR TEST HYPOTHESIS Consider a sample of 54 football games, where 33 of them were won by the home team. Use a 0.10 significance level to test the claim that the probability that the home team wins is greater than one-half.Identify the null and alternative hypotheses for this test. Choose the correct answer below.A. Ho: p=0.5H₁: p0.5B. Ho: p=0.5H₁: p > 0.5C. Ho:p>0.5H₁: p=0.5D. Ho: p=0.5H₁: p<0.5Identify the test statistic for this hypothesis test.The test statistic for this hypothesis test is(Round to two decimal places as needed.)

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.

Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At 0.01 level of significance, you wish to test the claim that the proportion of all adults in the town that have been exposed to this strain of the flu is 8%.
