Using Excel to Find Normal Probabilities

Triglycerides are a type of fat in the bloodstream. The mean triglyceride level in the United States is 134 milligrams per deciliter. Assume the triglyceride levels of the population of the United States are normally distributed with a standard deviation of 35 milligrams per deciliter. You randomly select a person from the United States. What is the probability that the person’s triglyceride level is less than 80? Use Excel to find the probability.
