Asked by Annie
Please help with this question, THANK YOU in advance. A line should be over the top of both X’s.
In an English class last semester, Foofy earned a 76 (X = 85, Sx = 10). Her
friend, Bubbles, in a different class, earned a 60 (X=50, Sx = 4). Should Foofy
be bragging about how much better she did? Why?
