High level of blood cholesterol increases the risk of atherosclerosis, the thickening of the arteries that can reduce blood flow to the heart, brain, kidneys, etc. This increases the risk of heart attack, stroke, and kidney failure among other diseases. The cholesterol level for adult males of a specific racial group is approximately normally distributed with a mean of 4.8 mmol/L and a standard deviation of 0.6 mmol/L. a. An adult male has high risk if his cholesterol level is more 5.75 mmol/L. What is the probability of being at high risk? b. On the other hand, an adult male has low risk if his cholesterol level is 1 standard deviation or more below the mean. What is the proportion of the adult male population that are at low risk? *Show complete solution and brief explanation
