A random sample of games was collected to determine if there is a difference in the population ...

A random sample of games was collected to determine if there is a difference in the population proportion of seven-game series won by the home team. The data appear in the contingency table.

	Baseball	Hockey	Basketball	Total
Won by home team	23	70	70	163
Won by visiting team	21	41	15	77
Total	44	111	85	240

Select the appropriate critical value (CV), test statistic (TS), and conclusion. (Useα= 0.05.)

▸

CV = 7.378, TS = 10.212; the proportions of seven-game series won by the home team are not the same for all three sports.

▸

CV = 5.992, TS = 14.272; the proportions of seven-game series won by the home team are not the same for all three sports.

▸

CV = 5.992, TS = 14.272; the proportions of seven-game series won by the home team appear to be same for all three sports.

▸

CV = 7.378, TS = 4.231; the proportions of seven-game series won by the home team appear to be same for all three sports.
