Twenty-four coworkers want to see whether various routes differ in the time it takes to
get to work. Starting from points equidistant from work, eight coworkers take public
transportation, eight drive on the highway, and eight take back roads. Below are their
reported times in minutes for the commute:

a. What are the independent and dependent variables in this study?
b. State the null hypothesis and the research hypothesis.
c. Calculate F and compare it with the critical value of F at the .01 and .05 a levels. At what level of error can you reject the null hypothesis, if at all?
d. Prepare an ANOVA summary table of the results.
e. Write the results in APA journal format.
