Blood pressure and cholesterol Suppose that both blood pressure and cholesterol levels of adult women can be described with Normal models, and that the correlation between these variables is 0.60. If a woman's blood pressure places her at the 88th percentile, at what percentile would you predict her cholesterol level to be?

 Correlation: r = 0.60; Blood pressure at 88th percentile: zBP = 1.175Regression to the mean predicts that zC will be r times as far from 0 as zBP was.zC = 0.60 zBP = 0.60(1.175) = 0.705, so cholesterol will be approximately the 76th percentile.
