Chapter 15: Activity #4- Chi Square (worth 3points) This research is design to challenge our thinking about chi-square, sample size, and proportions. After completing the two problems use the information to answer the question below. Assume that a social psychologist is interesting in studying the possible effect of the home court advantage. a. In 50 home games, suppose that the team won 31 times and lost 19 times. Is this result sufficient to conclude that the team with more home games will win significantly more than would be expected by chance? Test at the .05 level of significance. Won Lost b. In 100 home games, suppose the team won 62 times and lost 38 times. Is this sufficient to conclude that the team with more home games will win significantly more than would be expected by chance. Test at the .05 level. Won Lost c. Note that the winning percentage for home games in part (a) is identical to the percentage in (b) (31/50 = 62% 62/100 = 62%). Although the samples have exactly the same winning percentages, one is significant and the other is not. Explain why the two samples resulted in different conclusions
