Question

An elevator in a building is limited to 16 people and the weight limit is 2000 pounds. Assume that the average weights of the people in the building is 140 pounds, that the standard deviation is 26 pounds, and that the distribution of weights is approximately normal. Suppose a random sample of 16 people in the building is selected. What is the probability that the sample mean weight will: A) Exceed 161 pounds? B) Be between 135 and 150 pounds?

Step 1

We are given a scenario where an elevator has a weight limit and we know the average weight of people in the building, along with the standard deviation. We are asked to find the probability that the sample mean weight of 16 randomly selected people will exceed Show more…
