1. Use Statistix to compare the mean sizes/mileages for levels 2 and 3 of your qualitative variable. In Statistix you will need to omit all level 1 observations in your data set to create this printout. Conduct the printout for a two-tailed test in Statistix Attach the printout here and answer the following questions.

State the appropriate hypotheses that you wish to test to conduct a two-tailed test to compare the population means. (2 points) Ho: ul- 12=0 Ha: p1- 12 0 b. State the rejection region you would use if you wanted to conduct a two-tailed test. You choose alpha. (2 points) (Assume for this problem that you are working with 40 degrees of freedom - I know you are not, but that is the row I want you to use in the table). C. Use the confidence interval on the printout to make an inference about which of the two populations means is larger. Make sure to state your measure of reliability. (2 points)
