Suppose that 14 individuals are randomly chosen. Let X = average percent of fat calories consumed for a sample of size 14 . Enter numbers as integers or fractions in "p/q" form, or as decimals accurate to nearest 0.01 . a. (.20) X ~ (pick one) v ( 0 0) b. (.20) Use the mean and standard deviation of X to determine the z value for X = 35 Z = c. (.20) Illustrate P(X 240) as an area by adjusting the slider along the horizontal axis to control the z value. Z = 0.00 0.300 0.2 0.1 - 2 1-1 12 OFill left Fill right d. (.20) What is the probability that the 36 balls traveled an average of greater than 240 feet? P(X > 240 ) = e. (.20) Find the 80th percentile of the distribution of the average of 36 fly balls. That is, find x so that P(X
