For #1- 9: The Psychology Department faculty are wondering whether a free tutoring program will help boost grades in Introductory Psychology classes. We decide to try it out in Dr. Deuel's section. Using a Single Sample design with 28 participants they provide the program and then collect data on final grades. After the program, the sample mean was 88 and the sample standard deviation was 7. Conduct a t-test to determine if this is a significant difference from the population mean of 85 (the mean for ALL sections of Introductory Psychology from previous semesters). Set a= .05 and use a 2-tailed test. М -и estimated standard error =SM = In t = or SM 1. In statistical notion, what is your null hypothesis?
