possible Submit test An elevator has a placard stating that the maximum capacity is 3500 1b- 25 passengers. So, 25 adult male passengers can have a mean weight of up to 3500/25- 140 pounds. Assume that weights of males are normally distributed with a mean of 181 lb any a standard deviation of 37 Ib. a. Find the probability that 1 randomly selected adult male has a weight greater than 140 lb. b. Find the probability that a sample of 26 randomly selected adult males has a mean weight greater than 140 Ibj 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 140 lb is (Round to four decimal places as needed.) b. The probability that a sample of 25 randomly selected adult males has a mean weight greater than 140 la is (Round to four decimal places as needed.) c. Does this elevator appear to be safe
