Question
A researcher is interested in studying the average number of traffic violations received by male vs. female drivers. The researcher has a sample of 30 male drivers and 32 female drivers and conducts a two-sample t-test (two-tailed, alpha = .05). The researcher finds the following:
1. Male drivers have an average of 4 traffic violations every year.
2. Female drivers have an average of 2 traffic violations every year.
3. The standard error of the mean difference between male and female drivers (i.e., the se) is .50.
What are the degrees of freedom for this test? Enter your answer as a whole number with no decimal places (i.e., 10, not 10.01, not 10.0, not 10.1).
