- 7Consider a sample of 47 football games, where 28 of them were won by the home team. Use a 0.01 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. O A. Ho: p=0.5 H₁: p=0.5 ⒸB. Ho: p=0.5 H₁: p>0.5 O C. Ho:p>0.5 H₁: p=0.5 O D. Ho: p=0.5 H₁: p<0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho.

- K In a July 2017 report, a research firm stated that 39% of people from a certain region reported being harassed while online. An AP Statistics student decided to conduct her own survey at her high school of 3,260 students. She randomly selected 239 students to be surveyed and 99 of them stated that they had been harassed online. Does her survey suggest that the problem is worse at her school than it is for a typical person in the region? Determine the appropriate hypotheses. Ho P HA P (Type integers or decimals.) The test statistic is z = (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) State your conclusion. Use a = 0.05. the null hypothesis. There sufficient evidence to conclude that the proportion of students in the high school who were harassed while online is the proportion of people from the region being harassed while online.USE STATCRUNCH TO SHOW WORKWhich of the following p-values will lead us to reject the null hypothesis if the level of significance equals 0.025? a 0.015 b 0.150 c 0.250 d 0,051

Determine if voters’ opinions are independent or dependent of gender. Set up hypotheses; perform a test for independence; analyze all relevant aspects of your conclusion.use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.
