Epidemiology

Epidemiology.

The Centers for Disease Control and Prevention reported the percentage of children who had abnormal cholesterol levels according to body weight. Among biys, the percentages of abnormal cholesterol levels for normal, weight, overweight, and obese persons were approximately 15%, 25%, and 45%, respectively. Among girls, the corresponding percentages were approximately 15%, 25%, and 44%, respectively. Based on these data, is there a relationship between gender and cholesterol levels? How does body weight relate to cholesterol levels? Please use statistical terms (ex. frequency, distribution, mean, variance, standard deviation, range, variance, correlation, etc.) in your responses.
