The percent of fat calories that a person consumes each day is normally distributed with a mean of about 33 and a standard deviation of about ten. Suppose that 9 individuals are randomly chosen. Let X = average percent of fat calories. (a) Give the distribution of X. (Round your standard deviation to two decimal places.) X ~ ? v (b) For the group of 9, find the probability that the average percent of fat calories consumed is more than four. (Round your answer to four decimal places.) Graph the situation and shade in the area to be determined. none none 0.12 0.12 0.10 0.10 0.08 0.08 0.06 0.06 0.04 0.04 0.02 0.02| 20 30 40 10 30 40
