A course can be taken for credit either by attending lecture sessions in a classroom, or by doing online sessions. The instructor wants to know if these two ways of taking the course resulted in a significant difference in achievement as measured by the final exam for the course. Table 10.2 gives the scores on an examination with 45 possible points for one group of n, =9 students who took the course online, and a second group of n, =9 students who took the course by attending classroom lecture sessions. Do these data present sufficient evidence to indicate that the average grade for students who take the course online is significantly higher than for those who attend classroom lecture sessions?
