The percent of fat calories that a person in America consumes each day is normally distributed with a mean of about 36 and a standard deviation of 10. Suppose that one individual is randomly chosen. Let X=X= percent of fat calories. (a) Find the z-score corresponding to 27 percent of fat calories, rounded to 3 decimal places. 0.900Incorrect (b) Find the probability that the percent of fat calories a person consumes is more than 27. 81.59Incorrect (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). Shade: . Click and drag the arrows to adjust the values.
