High levels of cholesterol in the blood increase the risk of heart disease. For 14-year-old boys, the distribution of blood cholesterol is approximately Normal with mean LaTeX: \mu=170 milligrams of cholesterol per deciliter of blood (mg/dl) and standard deviation LaTeX: \sigma=30 mg/dl.
1. People with cholesterol levels between 200 and 240 mg/dl may require medical attention. What percent of 14-year-old boys have blood cholesterol between 200 and 240 mg/dl?
Assessing Normality can be a very useful tool in statistics (we haven't yet covered all the reasons why, but on reason is because it helps with inference procedures). In the lesson today, we discussed a few things that can help you decide if a distribution is approximately Normal.
2. Explain the characteristics that you can test for to determine if a distribution is approximately normal.
