CLT Problem The percent of calories from fat that a person in the United States consumes has a mean of about 36 and a standard deviation of 10. Suppose that sixteen (16) individuals are randomly chosen. Let = the average percent of calories from fat mean for the averages = 36 standard deviation for the averages = n = 16

CLT Problem For a group of 16 people, find the probability that the average percent of calories from fat consumed is more than 30. Probability Statement: P(X-bar > 30) = 0.9918 Calculator steps: 2nd,DISTR,normalcdf(30,1E99,36,10/sqrt(16)),Enter

CLT Problem Find the probability that the average percent of calories a person consumes from fat is between 30 and 40. Probability Statement: P(30 < X-bar < 40) = 0.9370 Calculator steps: 2nd,DISTR,normalcdf(30,40,36,10/sqrt(16)),Enter

CLT Problem Find the first quartile for the average percent of calories from fat. Let k = the first quartile (25th %ile) Probability Statement: P(X-bar < k) = 0.25 Calculator steps: 2nd,DISTR,invNormf(0.25,36,10/sqrt(16)),Enter
