The United States Department of Agriculture (USDA) found that the proportion of young adults ages 20-39 who regularly skip eating breakfast is 0.238. Suppose that Lance, a nutritionist, surveys the dietary habits of a random sample of size n 500 of young adults ages 20-39 in the United States. Apply the cnormal to find the probability that the number of individuals, X, in Lance's sample who regularly skip breakfast is greater than 124. You may find table of critical values...
