(GPA ranges from 0 to 4, and 2 is a bare pass.) (a) True or false: more students reported a GPA in the range 2.0 to 2.1 than in the range 1.5 to 1.6. (b) True or false: more students reported a GPA in the range 2.0 to 2.1 than in the range 2.5 to 2.6. (c) What accounts for the spike at 2?

UCM recently randomly sampled seven students and analyzed grade point average (GPA) and number of hours worked off-campus per week. UCM wants to predict GPA. The following data were observed: GPA HOURS 3.14 25 2.75 30 3.68 11 3.22 18 2.45 22 2.80 40 3.00 15 2.23 29 3.14 10 2.90 0 In this study, the independent variable is the number of hours worked off-campus per week. True False
In order to study the impact of extracurricular activities on the GPAs of high school students, data on a large group of high school students was collected about their participation in any extracurricular activity or activities and their GPAs. This is an example of an Observational Study.
