Let’s assume that according to UCSC summary statistics, the average student missed 2.7 classes during winter quarter. Imagine that you are working with a randomly selected group of six students who are on academic probation and find that their missed number of classes during winter quarter were 6, 3, 7, 6, 4, 5. You wonder if their absences differ from that of the general UCSC student population. Conduct a two-tailed, single-sample t-test, p<.05.
