Hypokalemia blood potassium is diagnosed when levels are below 3.5mEq/dl. Let's assume that we know a patient whose measured potassium levels vary daily according to a normal distribution N( μ = 3.8,0 = 0.2). a. If only one measurement is made, what is the probability that this patient will be diagnosed with Hypokalemia? b. Instead, if measurements are taken on 4 separate days, what is the probability of a diagnosis with Hypokalemia?
