A course can be taken for credit either by attending lecture sessions at fixed times and days, or by doing online sessions that can be done at the student's own pace and sched- ule. The course coordinator wants to determine 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 with conventional lectures. 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 a conventional class?
