There are 11 persons that would be classified as morbidly obese. The percentage of persons in this sample who are morbidly obese is then 0. The percentage of adults with unhealthy total cholesterol levels is then 21 93 0. Since there are a total of 25 CEOs, we simply divide each of the numeric labels on the vertical frequency axis.
These are usually converted to decimals, rather than being listed as fractional values. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

Share :. B True. C False. D True. A B C True. It increased in 5 of those years. A B C They both have the same shape skewed to the right , because the class width in the histogram is 5, as is each line for each stem 5.
The number of leaves in each stem is the frequency of occurrence, which is also the height of the bars in the histogram. Section 2. Understanding the Concepts 3. Graph A presents an accurate picture, because the baseline is at zero. Graph B exaggerates the decline, becausethe baseline is above zero. The bar graph does presents a more accurate picture because its baseline is correctlyplaced at 0. The time-series plot exaggeratesthe rate of the increase.
The bar graph is more accurate. The pictures of the dollars make the differenceappear much larger than the bar graph does. The reason is thatboth the height and length of the dollar has been increased. Graph B presents the more accuratepicture, because it follows the area principle. In Graph A , the area of the larger image is about four times that of the smaller image.
This exaggerates the difference. The bar graph is an accurate depictionbecause the baseline is at 0. It is misleading because the baseline is not placed at zero. A It is misleading because you can see the tops of the bars in the three-dimensional graph. This often causes them to look shorter than they really are. The plot on the left has its baseline at zero, and presents an accurate picture. The plot on the rightexaggerates the increase.
Option ii is the correct one, because it correspondingly matches up with graph A which is the correct one. Graph B does not have a baseline value of zero, so it gives the incorrect description of option i. A B Yes, it makes the differences look smaller, because the scale on the y-axis extends much farther than the largest bar height. C Figure 2. It has a baseline of zero unlike Figure 2. The classes are: 5.
