The table below lists the number of games played in a yearly best-of-seven baseball championship series, along with the expected proportions for the number of games played with teams of equal abilities. Use a 0.05 significance level to test the claim that the actual numbers of games fit the distribution indicated by the expected proportions. Games Played 4 5 6 7 Actual contests 18 19 20 36 2 4 5 5 Expected proportion 16 16 16 16 Determine the null and alternative hypotheses. Ho The observed frequencies agree with the expected proportions. H: At least one of the observed frequencies do not agree with the expected proportion Calculate the test statistic, x. x=(Round to three decimal places as needed.)
