Question

Values of HDL cholesterol levels (good cholesterol) vary in a certain population with values according to a normal distribution of mean 32.0 and standard deviation 4.0 ml/dl.

Answer the following questions:

a. What is the probability of randomly selecting an HDL cholesterol measurement with cholesterol below 30.0 knowing that the value is below 34.0 ml/dl?
B. What is the probability of randomly selecting an HDL cholesterol measurement with cholesterol below 26.9 ml/dl?
c. below what cholesterol are 70% of cholesterol measurements?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
