R1

A study was conducted for an aviation safety agency in which they surveyed thousands of passengers at airports across Europe. In this study, the "mass" for a passenger includes the weight of the passenger and all of the passenger's carry-on items, including infants without their own seats. For the 5,904 adult male passengers measured in summer, the sample mean and standard deviation for this mass were 88.8 kg and 16.1 kg, respectively. A USE SALT (a) Construct a 95% confidence interval (in kilograms) for the population mean mass for adult male passengers in summer.
