Answer these problems by calculating a t value and comparing it to the critical value for a two-tailed test at the .05 level. (Note: You can save time by using the means and standard deviations you calculated for the dormitories called Turck and Kirk Halls for previous exercises.)

a. Would you retain or reject the null hypothesis that the population mean for Turck Hall is 16?

b. Would you retain or reject the null hypothesis that the population mean for Kirk Hall is 11?
