The accompanying table lists body temperatures (in F) obtained from randomly selected subjects. Using a

0.05 significance level, test for an interaction between gender and smoking, test for an effect from gender, and test for an effect from smoking. What do you conclude?

First test for an interaction between the two factors. Determine the null and alternative hypotheses.

Determine the test statistic.

Determine the P-value.

Determine the proper conclusion at the significance level
