Students in a mathematics class were given an exam and then retested monthly with equivalent exams. The average score S (on a 100-point scale) for the class can be modeled by S = 80 – 14ln(t + 1), 0

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades:4.0 in a 5 credit Math course2.1 in a 2 credit Music course2.5 in a 5 credit Chemistry course3.3 in a 6 credit Journalism courseWhat is the student's GPA for that term? Round to two decimal places. Student's GPA =

Given R² = 0.3129 and SSR = 88.68, compute SST. SST = Round to 2 decimal places.

You put n = 20 rats in a cage that is in a room with a 65-degree temperature.  The next day you put them in a cage with a 70-degree temperature.  On the final day of the study you put them in a cage with a 75-degree temperature.  For each of the three days, you measure how many minutes of each hour they spent running on their exercise wheel.  To compare the time they spent running on the wheel between the three different days (in other words, between the three different temperatures of 65, 70, and 75 degrees), what kind of hypothesis test should you do? One-Factor, Independent-Measures ANOVA One-Factor, Repeated-Measures ANOVA Correlation/Regression Chi-Square Goodness of Fit
