A report summarizing scores for students on a verbal aptitude test x and a math aptitude test y gives the following results: x = 480, sx = 80, y = 500, sy = 120, r = 0.6. Now switch the variables: let x be the math aptitude score, and calculate the prediction equation.

Aspirin prevents blood from clotting and helps prevent strokes. The Second European Stroke Prevention Study asked whether adding another anticlotting drug named dipyridamole would make a difference for patients who had already had a stroke.

The pH of a liquid is a measure of its acidity or alkalinity. Pure water was a pH of 7, which is neutral. Solutions with a pH less than 7 are acidic while solutions with a pH greater than 7 are alkaline. A biologist was interested in testing the purity of lake water in Florida. A random sample of 58 lakes was taken, and the pH of water in each lake was recorded. The sample of lakes had an average pH of 6.567 with a standard deviation of 1.861.
