The аverаge number оf English cоurses tаken in a twо–year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of 3 English courses with a standard deviation of 0.8. The females took an average of 4 English courses with a standard deviation of 1.0. Is this evidence of a difference in the average number of English courses taken by males and females?
