The United States Department of Agriculture (USDA) found that the proportion of young adults ages 20-39 who regu. 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 central limit theorem to find the probability that the number of individuals, X, in Lance's sample who regular skip breakfast is greater than 122. You may find table of critical values helpful. Express the result as a decimal precise to three places.
