A researcher wants to see if gender plays a role in where we sit in a restaurant. An analysis of survey data yields the following contingency table, chi-squared value, and p-value:
Tabulated statistics: Gender, Seating
Rows: Gender Columns: Seating

All 32 46 147 225
Pearson Chi-Square = 2.469, DF = 2, P-Value = 0.291
