2. The correlation between the three courses. You should highlight the correlation in the output and send the output file to BeachBoard or copy and paste the output in a Word document.

3. T-test to see if there is a significant difference between boys and girls in Math, Physics, and Chem. You should highlight the t value and the number that shows the difference is significant or not in the output and send the output file to BeachBoard or copy and paste the output in a Word document.

4. Create a new variable named GPA to calculate the average of each student’s score in the three courses. This will be saved in the data file so you should submit your datafile to BeachBoard.
