Question

The table below lists the number of games played in a yearty 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 19 21 22 38 Determine the null and altemative hypotheses. Ho: The observed frequencies agree with the expected proportions H1: At least one of the observed frequencies do not agree with the expected proportions. Calculate the test statistic, X2. Round to three decimal places as needed.

Explanation / Answer

The statistical software output for this problem is:

Chi-Square goodness-of-fit results:
Observed: Yes
Expected: No

Hence,

X2 = 8.216

P - Value = 0.0418

Conclusion: Option C is correct.

Evidence: Option B is correct.

N DF Chi-Square P-value 100 3 8.216 0.0418
