Shoppers at a mall have a mean weight of 70 kg with a standard deviation of 10 kg. An elevator at the mall
holds a maximum of 6 people, and safety engineers are curious about the average weight of shoppers on a full
elevator. Suppose that we take random samples of 6 shoppers and calculate the mean weight 2 of the shoppers
in each sample.
Calculate the mean and standard deviation of the sampling distribution of
You may round to one decimal place.
