Histograms of random sample data are often used as an indication of the shape of the underlying population distribution The histograms on the next page are based on random samples of size 30, 50, and 100 from the same population (a) Using the midpoint labels of the three histograms, what would you say about the estimated range of the population data from smallest to largest? Does the bulk of
