a. Determine the simple regression equation (by hand) that best fits this data.c
b. Calculate and interpret the R-Square and the adjusted R-Square for this model.
Usng a 0.05 level of significance, test to see if this is a good or bad model using the
correlation test.
d. Using a 0.05 level of significance, test to see if this is a good or bad model using the
t-test on slope!
e. Using a 0.05 level of significance, test to see if this is a good or bad model using the
F-test on slope
f. Looking over your full results, what can you conclude about the relationship between
hours worked per day (X) and final quiz scores (Y)?
4. Use Excel to check your answers for question 3. Make sure to turn in your Excel spread
sheet and identify output that relates to the results above
