A controversial issue in the sport of professional soccer is the use of instant replay for making difficult goal line decisions. Each person in a representative sample of 102 players, fans, coaches, and officials was asked his or her opinion about the use of instant replay for goal-line decisions. The data are summarized in the two-way frequency table below. Opinion Favor use Oppose use Players 22 2 Fans 18 Coaches 15 26 Officials 10 In testing to see whether opinion with respect to the use of instant replay is independent of the category of the person interviewed, a chi-square test statistic of 27.99 and a p - value less than 0.001 were calculated. Which of the following statements is correct? O The number of degrees of freedom for the test is 8 - 1 = 7. O The chi-square test shows that fans favor the use of instant replay. O The small p - value suggests that there is evidence of an association between category and opinion about the use of instant replay O The null hypothesis states that there is an association between category and opinion about the use of instant replay, and the small p - value suggests that the null hypothesis should be rejected. O The chi-square test should not have been used because 2 of the counts in the table are less than 5. Category
