Winning team data were collected for teams in different sports, with the results given in the accompanying table. Use a 0.05 significance level to test the claim that home/visitor wins are independent of the sport. Given that among four sports I clouded here, baseball is the only sport In which the home team can modify field dimensions to favor its own players, does it appear that baseball teams are effective in using this advantage? ifentify the test statistic identify the p value ifentify the null and alternative hypothesis

- What is meant by the sample space of an experiment?List the sample space of each experiment. Selecting a letter of the alphabetA machine in a factory must be repaired if it produces more than 10% defectives in a day. A random sample of 100 produced items contains 15 defectives, and the supervisor says that the machine must be repaired. Given the aforementioned information and the hypotheses H0: p ≤ 0.1 and H1: p > 0.1, does the sample support the supervisor's decision at the 0.01 significance level?

- To test the fairness of law enforcement in its area, a local citizens’ group wants to know whether women and men are unequally likely to get speeding tickets. Five hundred randomly selected adults were phoned and asked whether or not they had been cited for speeding in the last year. Using the results in the following table and a 0.100.10 level of significance, test the claim of the citizens’ group. Let men be Population 1 and let women be Population 2. Speeding Tickets Ticketed Not Ticketed Men 5555 174174 Women 4545 226226 Step 2: compute test value.. round to 2 decimal places Step 3: draw a conclusion and interpret the conclusion.The production numbers from four different machines with the same features in three different factories are given in the table below. In the hypothesis test of whether there is a difference between the production numbers of factories (columns) at the 5% significance level, which of the following is the F table value?The U.S. Census Bureau conducts annual surveys to obtain information on the percentage of the voting-age population that is registered to vote. Suppose that 713 employed persons and 613 unemployed persons are independently and randomly selected and that 338 of the employed persons and 244 of the unemployed persons have registered to vote. Can we conclude that the percentage of employed workers ( p1 ), who have registered to vote, exceeds the percentage of unemployed workers ( p2 ), who have registered to vote? Use a significance level of α=0.1 for the test. Step 1 of 6 : State the null and alternative hypotheses for the test. Step 2 of 6 : Find the values of the two sample proportions, pˆ1p^1 and pˆ2p^2.
