How many degrees of freedom are there when we conduct a chi-square analysis of this crosstab? 2. Based on the Pearson chi-square statistic:  Is the relationship between gender and smoking statistically significant at the .01 level? Do we accept (fail to reject) or reject the null hypothesis? How did you reach this conclusion?
