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?
Thank you for the opportunity to help you with your question!
the above data can demand improvement in the service deliverly from the airline company.this is because of increased traffic of passengers and as a result they have to improve their capacity due to the increased demand
