So, 26 adult male passengers can have a mean weight of up to 3700 divided by 26 equals 142 pounds. Assume that weights of males are normally distributed with a mean of 187 lb and a standard deviation of 36 lb. a. Find the probability that 1 randomly selected adult male has a weight greater than 142 lb. b. Find the probability that a sample of 26 randomly selected adult males has a mean weight greater than 142 lb. c. What do you conclude about the safety of this elevator?

The probability that a sample of 26 randomly selected adult males has a mean weight greater than 142 lb is 1.0000. (Round to four decimal places as needed.) Part 3 c. Does this elevator appear to be safe? A. Yes, because there is a good chance that 26 randomly selected people will not exceed the elevator capacity. B.
