Suppose a pilot study is conducted using data from 10 heavy ice-cream eating students who just bought four-scoop banana splits! There is a concern that eating too much ice cream could raise cholesterol levels into the "borderline high" range of more than 200 mg / 100 dl3. The study measures blood cholesterol levels on the 10 ice cream eaters with the following measurements:
189, 143, 258, 238, 229, 161, 278, 252, 220, 179
Go through "The Drill". Can we extrapolate our conclusions to all ice cream eaters?
