Charity Navigator is America's leading independent charity evaluator. The following data show the total expenses ($), the percentage of the total budget spent on
administrative expenses, the percentage spent on fundraising, and the percentage spent on program expenses for 10 supersized charities (Charity Navigator website).
Administrative expenses include overhead, administrative staff and associated costs, and organizational meetings. Fundraising expenses are what a charity spends to raise
money, and program expenses are what the charity spends on the programs and services it exists to deliver. The sum of the three percentages does not add to 100% because
of rounding. Do not round your intermediate calculations.

An Internet Service Provider (ISP) offers three plans, High Speed (H), Medium Speed (M) and Low Speed (L). Each customer has the option of changing plan
each month, and using past data they have estimated the proportion of customers who change between plans as follows:
0.16 of those on H change to M, 0.12 change to L.
0.27 of those on M change to H, 0.09 change to L.
0.07 of those on L change to H, 0.27 change to M.
All other customers stay on the same plan.

- In 2010, the U.S. Congress passed the historic health care reform bill that will provide some type of coverage for the 32 million Americans currently without health care insurance. Just how widespread is the lack of medical coverage? The media claim that the segments of the population most at risk for disease and thus needing healthcare are women, children, the elderly and the poor.

Alumni donations are an important source of revenue for colleges and universities. If administrators could determine the factors that could lead to increases in the percentage of alumni who make a donation, they might be able to implement policies that could lead to increased revenues. Research shows that students who are more satisfied with their contact with teachers are more likely to graduate. As a result, one might suspect that smaller class sizes and lower student/faculty ration might lead to a higher percentage of satisfied graduates, which in turn might lead to increases in percentage of alumni who make a donation. Joseph is feeling an extra pressure to increase total giving to the university because of recent budget cuts. Joseph is also feeling pressured to increase the percentage of alumni to give.
