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 in areas like cost
Thank you for the opportunity to help you with your question!
the mean weight of the population has increased from 166.3 Ibs to 172.55 Ibs. this could have an impact on the capability of the aircraft to handle such an increase in the weight of passengers. therefore, the airline firm should determine whether the safety of passengers is at risk. this will entails measures such as acquiring a new aircraft that can handle increase in weight of passengers in the future. when this happen, the fixed costs of the airline will increase if it was to buy another aircraft. the firm should consult experts to determine how a change in fixed costs will affect the profitability of the firm.
