Interpretation The following histograms are based on different random samples of size 100 drawn from the same population.

(a) Identify the midpoint of the class with the highest frequency in each of the three histograms.

(b) Using the class midpoints, what is the range of data shown in each histogram?

(c) Which of the histograms are more clearly skewed right?

(d) Based on your study of random sample in Chapter 1, is it surprising to see the variations in the samples as displayed in the histograms? The original population from which the samples were drawn is skewed right with a high frequency near 4.

Do all three random samples seem to refl ect these properties equally well?
