A researcher is interested in understanding whether the mean time to complete a four-year college degree varies based on gender. She draws a sample of 12 college graduates-- 6 men and 6 women, and asks them how many years they took to finish their degree. Assuming that the data are drawn from a normal distribution, test the null hypothesis of no difference in mean years to degree completion between men and women. Show all your work.
