7. Consider the following data set: Time (hrs) Time (mins) GPA 1 60 2 2 120 2.2 2.6 156 2.3 3.4 204 2.7 Time 135 GPA=2.3 Time = 2.25 - STime = 1.0116 | STime = 60.6960 | SGPA = 0.2944 where Time (mins) is the amount of time in minutes. In other words, Time (hrs) & Time (mins) are the same variable that are measured in different units. In an in-class example, we found that the sample covariance between time (hrs) and GPA equals .2867, and the sample correlation coefficient between these two variables is .9626. In this problem, calculate the sample covariance and correlation coefficient between time (mins) and GPA. Comment on the findings.
