Question

Suppose that the creatine kinase levels among healthy males are normally distributed with a standard deviation of

units/L. Research shows that exactly

of the healthy males have a creatine kinase level above

152

units/L. What is the mean creatine kinase level in healthy males? Carry your intermediate computations to at least four decimal places. Round your answer to at least one decimal place.

units/L

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.
