An attempt was recently made to verify whether female students are more serious about their study as compared to the male students in IUT. To study this claim, the university appointed a researcher to obtain sample of per day study time of the fourth year students. The researcher found the following data about the per day study time for both the female and male students.

Female students / Male students Sample size 55 / Sample size 72 Sample mean 10.80 / Sample mean 12.20 Sample variance 0.90 / Sample variance 1.1
