The population of weights for men attending a local health club is normally distributed with a mean of 175-lbs and a standard deviation of 29-lbs. An elevator in the health club is limited to 32 occupants, but it will be overloaded if the total weight is in excess of 5984-lbs. Assume that there are 32 men in the elevator. What is the average weight beyond which the elevator would be considered overloaded? average weight = Ibs

Question
**Problem Statement:**

The population of weights for men attending a local health club is normally distributed with a mean of 175 lbs and a standard deviation of 29 lbs. An elevator in the health club is limited to 32 occupants, but it will be overloaded if the total weight exceeds 5984 lbs.

**Questions:**

1. **Determine Average Weight Limit:**
   - Assume that there are 32 men in the elevator. What is the average weight beyond which the elevator would be considered overloaded?
   - **Average weight = _____ lbs**

2. **Probability of Exceeding Weight:**
   - What is the probability that one randomly selected male health club member will exceed this weight?
   - **P(one man exceeds) = _____**
   - (Report answer accurate to 4 decimal places.)

3. **Probability of Elevator Overload:**
   - If we assume that 32 male occupants in the elevator are the result of a random selection, find the probability that the elevator will be overloaded.
   - **P(elevator overloaded) = _____**
   - (Report answer accurate to 4 decimal places.)

4. **Frequency of Overload:**
   - If the elevator is full (on average) 2 times a day, how many times will the elevator be overloaded in one (non-leap) year?
   - **Number of times overloaded = _____**
   - (Report answer rounded to the nearest whole number.)

5. **Safety Concern Evaluation:**
   - Is there reason for concern?
     - ☐ yes, the current overload limit is not adequate to ensure the safety of the passengers
     - ☐ no, the current overload limit is adequate to ensure the safety of the passengers
