Suppose the following data show the average attendance for the 14 teams in the International League. Also shown are the teams records; w denotes the number of games won, L denotes the number of games lost, and PCT is the proportion of games played that were won.

Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) p-value = State your conclusion. O Do not reject H.. There is sufficient evidence to conclude that the mean attendance values are not equal for the three divisions. O Do not reject H.. There is not sufficient evidence to conclude that the mean attendance values are not equal for the three divisions. O Reject H,. There is sufficient evidence to conclude that the mean attendance values are not equal for the three divisions. O Reject H,. There is not sufficient evidence to conclude that the mean attendance values are not equal for the three divisions. (b) Use Fisher's LSD procedure to determine where the differences occur. Use a = 0.05. Find the value of LSD for each pair of divisions. (Round your answers to two decimal places.) North and South LSD North and West LSD = South and West LSD = Find the pairwise absolute difference between sample attendance means for each pair of divisions. (Round your answers to the nearest integer.) = = Which attendance means differ significantly? (Select all that apply.) O There is a significant difference in mean attendance between the North division and the South division. O There is a significant difference in mean attendance between the North division and the West division. O There is a significant difference in mean attendance between the South division and the West division. O There are no significant differences.
