The human resource group for a company collected data summarizing the educational level and tenure of the company's employees. The results are in the accompanying data table. None AA BA MA |PHD 5 years 113 26 68 A 0 The different educational levels are no college degree (None), associate's degree (AA), bachelor's degree (BA), master's degree (MA), and PhD. The three levels of tenure are less than 1 year, between 1 and 5 years, and more than 5 years. Complete parts a through e below. (%) None AA BA MA PhD 5 years 1% 1% 1% % (Round to the nearest tenth as needed.) b) Looking at the column percentages in part a, does the tenure distribution for each educational level look the same? O A. Yes, all percentages are roughly the same across all categories. O B. No, more than 65% of those with a PhD have been with the company longer than 5 years, but less than 15% of those without a degree have been there that long. O C. No, more than 65% of those with no college degree have been with the company longer than 5 years, but less than 15% of the PhDs have been there that long O D. Yes, around half of the employees at each educational level have been with the company between 1 and 5 years. c) Make a stacked bar chart showing the tenure distribution for each educational level. Let N represent None. Let the lower, middle, and upper portions of the bars represent the tenures 5 years, respectively. Choose the correct chart below. O A. OB O C. 100- 100 100 80- Percent 40- AA BA MA Pho AA BA MA PhD N AA BA MA PHD d) Is it easier to see the differences in the distributions using the column percentages or the stacked bar chart? O A. Although the column percentages are more accurate, the stacked bar chart is much more attractive. O B. It is possible to see the differences in the stacked bar chart, but the column percentages make the differences much easier to compare. O C. Although the chart displays the data in a smaller space, the table gives all the exact percentages. O D. It is possible to see the differences in the column percentages, but the stacked bar chart makes the differences much clearer. e) How would a mosaic plot help to accurately display these data? O A. A mosaic plot would display the data side by side for easier comparisons O B. A mosaic plot would make the widths of the bars proportional to the number of employees with each educational level, so the areas of the plot representing each cell would then reflect the cell percents accurately. O C. A mosaic plot would use wedges to display the data as portions of a whole for easier comparisons O D. A mosaic plot would display the row, column, and total percents for each degree type, so the plot representing each cell would then show all the information for each cell
