How do you go from 0.5833 to 0.7202
Given data :
Use the Standard Normal Distribution to answer the following question: The mean serum high-density-lipoprotein (HDL) cholesterol of females who age between 20-29 years old is μ= 53.0 unit of measurement. The standard deviation is σ = 12.0 units of measurement. Knowing that the serum HDL cholesterol in this population of females who age between 20 and 29 years old is normally distributed.
a. If one 20-29 year old genetic female is randomly selected, what is the probability that their HDL cholesterol is less than or equal to 60? Calculate z-score and then use the z-value table to obtain the probability.
b. If one 20-29 year old genetic female is randomly selected, what is the probability that their HDL cholesterol is between 29 and 77?
