2. The capacity of a passenger elevator is listed at 1950 kg. Assume that the random variable representing passengers' mass follows a nomal distribution with mean- 73 kg and standard deviation 14 kg. This problem asks you to apply concepts related to linear functions of randomm variables What is the probability that the total load exceeds the capacity if 25 people squeeze onto the elevator? a. b. If the probability that these 25 people exceeded the capacity was 10 what would the capacity be?
