**Chi-Square Goodness-of-Fit Test Question** Find the value of the chi-square test statistic for the goodness-of-fit test. The following table is obtained from a random sample of 30 absences. You wish to test the claim that the absences occur on the five days with equal frequency. What is the value of the \( \chi^2 \) test statistic? The observed frequencies and the expected frequencies are shown to the right. | Day | Mon | Tue | Wed | Thur | Fri | |---------|-----|-----|-----|------|-----| | Number Absent | 8 | 9 | 2 | 10 | 1 | **Observed and Expected Frequencies:** - **Observed Frequency (O):** - 8 - 9 - 2 - 10 - 1 - **Expected Frequency (E):** - 6 - 6 - 6 - 6 - 6 **Options:** - A. \( \chi^2 = 17.500 \) - B. \( \chi^2 = 7.000 \) - C. \( \chi^2 = 8.750 \) - D. \( \chi^2 = 11.667 \)
