For each of the following pairs of variables, indicate whether you would expect a positive correlation, a negative correlation, or a correlation close to 0. Explain your choice. (a) score on the math section of the ACT exam and college GPA Ⓒ We expect a positive correlation since we expect students with higher scores on the math section of the ACT to also have higher college GPAS. We expect a positive correlation since we expect students with higher scores on the math section of the ACT to have lower college GPAS. Ⓒ We expect a negative correlation since we expect students with higher scores on the math section of the ACT to also have higher college GPAs. Ⓒ We expect a negative correlation since we expect students with higher scores on the math section of the ACT to have lower college GPAS. We expect a correlation close to zero since we expect don't expect to see any relationship between a student's score on the math section of the ACT and his or her college GPAs. (b) time spent studying and time spent working by college students Ⓒ We expect a positive correlation since we expect students who spend more time studying to spend more time working as well. We expect a positive correlation since we expect students who spend more time studying to spend less time working. We expect a negative correlation since we expect students who spend more time studying to spend more time working as well. O We expect a negative correlation since we expect students who spend more time studying to spend less time working.
