"Workers at a site have a mean weight of 70 kg with a standard deviation of 10kg. An elevator at the site holds a maximum of 6 people, and safety engineers are curious about the average weight of workers on a full elevator. Suppose that we take random samples of 6 workers and calculate the mean weight of the workers in each sample. Calculate the standard deviation of the sampling distribution of mean weight.

Answer:

sorry need point

Step-by-step explanation:

sorry sorry again

For the sampling distribution,

The standard deviation is 4.08 and for the sampling distribution, the formula of the population variance is 16.67 and this can be determined by using the given data.

Given

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.
