According to the USDA, the mean calorie intake for males, ages 20 to 39 years old, is 2816 with as standard deviation of 80.8 (assume a normal distribution). A health site online states that an inactive man needs to take in 2600 calories per day to maintain his current weight. What is the probability that a random sample of 40 males, ages 20-39, would have an average maximum calorie intake of 2600 calories per day?
