Did you know that arsenic is a compound that is found naturally but in very low concentrations? Suppose that arsenic levels in healthy adults is normally distributed with population mean of 3.2 micrograms per deciliter (ug/dl) and a population standard deviation of 1.5 ug/dl. If a healthy adult was randomly selected what is the probability that their arsenic level was at least 0.45 ug/dl? To do this solution must do it in the three parts given here as: Part A: Denoting what was asked to be found Part B: Give a full /complete quick graph that depicts the representation properly Part C: Give full calculator syntax including answer as well |
