Once we have a frequency distribution or a relative frequency distribution, we can put the information in graphical form by constructing a _____. A histogram is constructed by drawing a rectangle for each class. The heights of the rectangles are equal to the frequencies or the relative frequencies, and the widths are equal to the class width.

5. Calculate the relative frequency that 6 or more of the 10 salespeople laid off are 55 or older. 6. Combine your results with the rest of the class to obtain a more accurate relative frequency. Theory tells us that, in the long run, only about 1.6 times in 100 would you see 6 or more people 55 or older out of 10 if only chance were involved.
