- If a distribution is bimodal explain why a frequency histogram would make the distribution appear unimod: if a large enough class width is used Should such a class width be used? Explain. Choose the correct answer below. A. If a large enough class width is used then the space between the two modes could be included in the same classes which include most of the data. It would be dishonest to use such a class width because it would make the distribution appear unimodal. B. If a large enough class width is used the data for each mode would be displayed with a single class, making it appear to be two separate unimodal distributions...would be okay to use such a class width because the information presented I is still accurate. C. If a large enough class width is used the data for each mode would be displayed with a single class, making it appear to be two separate unimodal distributions...would be dishonest to use such a class width because it is an inaccurate representation of the distribution. D. If a large enough class width is used, then the space between the two modes could be included in the same classes which include most of the data. It would be okay to use such a class width because the information presented is still accurate.
- Explain why three-dimensional graphs can be misleading . What would be a better type of graph to use? Choose the correct answer below. A. Three-dimensional graphs can be misleading because the perspective makes it difficult to tell how the bottoms of the boxes line up with the vertical axis. A time-series plot is a better type of graph because estimating the heights of the plotted points is much easier. B. Three-dimensional graphs can be misleading because they can make bimodal distributions appear unimodal. A time-series plot is a better type of graph because estimating the heights of the plotted points is much easier. C. Three-dimensional graphs can be misleading because there are only two axes in the graph , so there is no label for the third dimension of the boxes. A bar graph is a better type of graph because estimating the heights of the bars is much easier. D. Three-dimensional graphs can be misleading because the perspective makes it difficult to tell how the tops of the boxes line up with the vertical axis. A bar graph is a better type of graph because estimating the heights of the bars is much easier.

- For this exercise, the resale rate of a car is defined to be the percentage of the sticker price the car is worth 5 years later. The resale rates of the cars with the 5 best resale rates are described by the bar graphs. Complete a parts (a) through (e)below. (Type a whole number.) C A. The graph whose vertical axis begins at 40, because when the vertical axis begins at a nonzero value, the difference between the heights of the bars is emphasized The car's resale rate is approximately 53% B. The graph whose vertical axis begins at 0, because when the vertical axis begins at 0. the difference between the heights of the bars is emphasized. The car's resale rate is approximately square % d. If the base price of Car C is 25,449 estimate its resale value. The resale value is approximately square . (Round to the nearest cent as needed.)
