description of an experiment done in a college science laboratory. A student affairs director is investigating whether the method of delivery will influence the retention of knowledge about on-campus social opportunities. Twenty-nine out of an incoming class of 1,200 new students were exposed to two different means of describing the campus opportunities: a student-created online video and a live lecture given by a professor. After each exposure, participants were asked individually to fill out separate 10-item memory quizzes based on the information given in each session. These quizzes were scored for the number of items correctly remembered. The questions will address each of the steps in the hypothesis testing. In the lab experiment, if Mvideo = 5.00 on sweetness and Mlecture = 4.75 on sweetness with an sD = 1.17, calculate the t test statistic
