Question
The following SPSS outputs come from a study looking at the relationships between auto accidents and biological sex. Auto accidents is treated like a categorical variable categories of accidents * Sex of insured Crosstabulation % within Sex of insured Sex of insured Male Female Total 19.1% 51.0% 29.9% 100.0% 30.6% 49.6% 19.8% 100.0% 24.9% 50.3% 24.7% 100.0% categories of accidents None 1-2 accidents 3-5 accidents Total Chi-Square Tests Asymp.

Based on the above outputs, what percentage of the females reported 3-5 accidents? 2. Based on the above outputs, what percentage of the entire sample had no accidents? 3. Based on the output, is there a statistical association between auto accidents and gender? 4. Based on the p-value, are auto accidents and gender independent of each other?Explanation / Answer
1. The % of females reported 3-5 accidents is 19.8%.
2. The % of the entire sample had no accidents is 24.9%.
3. Since p-value corresponding to Pearson Chi-square is 0.003 <0.01 ,conclude that there is a statistical association between auto accidents and gender.
4. Since p-value corresponding to Pearson Chi-square is 0.003 <0.01. the auto accidents and gender are not independent of each other.
