Assume that the amounts of weight that male college students gain during their freshman year are normally distributed with a mean of \( \mu=1.1 \mathrm{~kg} \) and a standard deviation of \( \sigma=5.6 \mathrm{~kg} \). Complete parts (a) through (c) below. a. If 1 male college student is randomly selected, find the probability that he gains between 0 kg and 3 kg during freshman year. The probability is (Round to four decimal places as needed.)

An elevator has a placard stating that the maximum capacity is \( 4300 \mathrm{lb}-28 \) passengers. So, 28 adult male passengers can have a mean weight of up to \( 4300 / 28=154 \) pounds. Assume that weights of males are normally distributed with a mean of 183 lb and a standard deviation of 38 lb . a. Find the probability that 1 randomly selected adult male has a weight greater than 154 lb . b. Find the probability that a sample of 28 randomly selected adult males has a mean weight greater than 154 lb . c. What do you conclude about the safety of this elevator? a. The probability that 1 randomly selected adult male has a weight greater than 154 lb is (Round to four decimal places as needed.)
