Question

In the 1960s, data were collected on the weights of people to determine the safe passenger capacity of aircraft. Using a random sample the mean weight was found to be 166.3 lbs.

In recent decades, the mean weight of the population has increased considerably, so we need to update our estimate of that mean.

Recently, a simple random sample of the weights of n = 40 people was collected and found to have a mean of = 172.55 lb.

How could these data be used to impact airline passengers' experiences? Consider areas such as ticket purchasing, cost, safety, customer service, or any other area that may come to mind.

Explanation / Answer

Solution:

We are given a mean weight of the people in the year 1960 as the 166.3 lbs. The mean weight of the population increased considerably and recently it is observed as 172.55 lb. This fact suggests that there would be an impact on the safe passenger capacity of aircraft. Due to increased weight of the aircraft passengers, the capacity of the aircraft would be decrease. Due to decreased aircraft capacity, the ticket purchasing capacity of the aircraft would be decrease and this would result in increasing the cost of the ticket for aircraft passengers. Also, due to this fact the customer service would be expensive as compared to previous years. Also, due to decreased capacity, the aircraft management needs to arrange more flights or increase the capacity of aircraft. So, there would be considerable changes required due to increased weight of the customers of aircraft.
