Is this conclusion statistically justified? Why or why not? (2) bj Help them determine which class Henry is doing better in. Show your calculations (rounded to two decimal places). You can either type out your calculations or take a picture of your handwritten calculations and insert an image file into the answer box. (6) Later you find out that Henry's Physics mark is an advanced university level course, and his chemistry mark is a high school level class. How does this change your interpretation if at all? (1)
