Submit an RScript file that includes your name in the file name (i.e. Kemper_HW9.R) and a word file with the results of each test you run and any resulting graphs. Testing assumptions: Just test, don't bother with transformations. High School GPA and University GPA Calculate the correlation coefficient. Express the results properly in words. (5 pts) Create a scatter plot comparing the two. (5 pts) Do a simple linear regression. Include an assessment of assumptions and express your results in words and mathematically. (5 pts for assessing each assumption, 5 pts for the regression analysis and 5 pts for the correct reporting of the results) Math SAT and Computer Science GPA Calculate the correlation coefficient.
