The exercise below relates to the following situation. ISO $9000$ is a series of international standards for quality assurance management systems. CEEM Information Services presents the results of a Quality Systems Update/Deloitte & Touche survey of ISO $9000$ -registered companies conducted in July $1993.$ Included in the results is a summary of the total annual savings associated with ISO $9000$ implementation for surveyed companies. The findings (in the form of a frequency distribution of ISO $9000$ savings) are given. Notice that the classes in this distribution have unequal lengths and that there is an open-ended class $(>\$ 500 \mathrm{~K})$ .

To construct a histogram for these data, we select one of the classes as a base. It is often convenient to choose the shortest class as the base (although it is not necessary to do so). Using this choice, the 0 to $\$10\mathrm{K}$ class is the base. This means that we will draw a rectangle over the $0$ to $\$10\mathrm{K}$ class having a height equal to $162$ (the frequency given for this class in the published data). Because the other classes are longer than the base, the heights of the rectangles above these classes will be adjusted. To do this we employ a rule that says that the area of a rectangle positioned over a particular class should represent the relative proportion of measurements in the class. Therefore, we proceed as follows. The length of the $\$10\mathrm{K}$ to $25\mathrm{K}$ class differs from the base class by a factor of $(25 - 10)/(10 - 0) = 3/2$ , and, therefore, we make the height of the rectangle over the $\$10\mathrm{K}$ to $25\mathrm{K}$ class equal to $(2/3)(62) = 41.333$ . Similarly, the length of the $\$25\mathrm{K}$ to $50\mathrm{K}$ class differs from the length of the base class by a factor of $(50 - 25)/(10 - 0) = 5/2$ , and, therefore, we make the height of the rectangle over the $\$25\mathrm{K}$ to $50\mathrm{K}$ class equal to $(2/5)(53) = 21.2$ .

Use the procedure just outlined to find the heights of the rectangles drawn over all the other classes (with the exception of the open-ended class, $>\$500To construct a histogram for these data, we select one of the classes as a base.

Draw the appropriate rectangles over the classes (except for $>\$500\mathrm{K}$ ).
