IS pure 27% 6-9 14% 10-12 22% 13 and over Interpretation A child between 10 and 12 years old looks at this probability distribution and asks, "Why are people more likely to buy toys for kids older than I am [13 and over] than for kids in my age group [10-12]?" How would you respond? 26. Health Care: Flu Based on data from the Statistical Abstract of the United States, 112th edition, only about 14% of senior citizens (65 years old or older) get the flu each year. However, about 24% of the people under 65 old get the flu each year. In the general population, there are 12.5% senior citizens (65 years old or older). (a) What is the probability that a person selected at random from the general population is a senior citizen who will get the flu this year? (b) What is the probability that a person selected at random from the general population is a person under age 65 who will get the flu this year? (c) Answer parts (a) and (b) for a community that is 95% senior citizens. (d) Answer parts (a) and (b) for a community that is 50% senior citizens. years 27. Focus Problem: Lie Detector Test In this problem, you are asked to solve part of the Focus Problem at the beginning of this chapter. In his book Chances: Risk and Odds in Everyday Life, James Burke says that there is a 72% chance a polygraph test (lie detector test) will catch a person who 15, fact, lying. Furthermore, there is approximately a 7% chance that the poly graph will falsely accuse someone of lying (a) Suppose a
