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 41 percent of fat calories, rounded to 3 decimal places. (b) Find the probability that the percent of fat calories a person consumes is more than 41. (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).
The percent of fat calories that a person in America consumes each day is
(a) Find the z-score corresponding to 41 percent of fat calories, rounded to 3 decimal places.
(b) Find the probability that the percent of fat calories a person consumes is more than 41.
(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).
(d) Find the maximum number for the lower quarter of percent of fat calories. Round your answer to 3 decimal places.
(e) Sketch the graph and write the probability statement.
