1. The data set on sheet #1 gives data on GPA category and number of hours studied. Construct comparative box plots of the data first GPA category. Then conduct two-sample t-test on the data for whether GPA category influences the number of hours studied. Be prepared to explain the results of the test and the meaning of the boxplots and how they relate to each other. Then redo the analysis by replacing the ordinal GPA category with a numerical dummy...
