1. Use Statistix to compare the mean sizes/mileages for levels 1 and 2 of your qualitative variable. In Statistix, you will need to omit all level 3 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 rejection region you would use if you wanted to conduct a twotailed comparison of population means. 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). b. State the assumptions necessary (in the words of the problem) to analyze the row of data you would use to interpret the pvalue or confidence interval for your comparing the two population means (5 points)
