1Q is normally distributed with a mean of 100 and a standard deviation of 15. Suppose one individual is randomly chosen. Let X = \Q of an individual. (a) Find the z-score for an IQ of 91, rounded to three decimal places. (b) Find the probability that the person has an IQ greater than 91. (c) Shade the area corresponding to this probability in the graph below. (Hint: The x-axis is the z- score. Use your z-score from part (a), rounded to one decimal place).
