Production Time A supervisor of a large factory takes a random sample of 100 laborers from the factory database.
He calculates the mean time taken by them to produce one unit of the product.
He records this value and repeats the process: He takes another random sample of 100 laborers and calculates the mean time taken.
After he has done this 500 times, he makes a histogram of the mean time taken. Is this histogram a display of the population distribution, the distribution of a sample, or the sampling distribution of means?
