For the following problem below, sketch the graph showing the mean and standard deviation, as well as the area in question. Show work to support your calculations. Suppose that the number of points that you score in a given quiz is approximately bell-shaped with a mean of 30 and a standard deviation of 6. Use the empirical rule to determine the following: a) What is the probability that you score between 18 and 42 points? b) What is the probability (two decimal places) that you score between 12 and 36 points? c) What is the probability (two decimal places) that you score less than 48 points?
