The following box plot shows the U.S. population for 1990†.Part (a)Are there fewer or more middle age adults (ages 33 − 50) than senior citizens (age 65 and over)? How do you know?There are more middle age adults, because 25% of the data falls in the range of 33 − 50, but less than 25% of the data is above 65.There are fewer middle age adults, because 25% of the data falls in the range of 33 − 50, and more than 25% of the data is above 65.    Part (b)12.6% are age 65 and over. Approximately what percent of the population are working age adults (above age 17 to age 65)? (Round your answer to one decimal place.) %

Which statement is NOT true of the aging American population as discussed in class?Group of answer choicesAmericans rank number one in life expectancy among the world's nations.By 2030 the older adult population is expected to make up about 20% of the population.Today, around 17% of the U.S. population is 65 years of age or older.The number of years people can expect to live has increased over 30 years since 1900 (and will continue to increase).

12.6% are age 65 and over. Approximately what percent of the population are working age adults (above age 17 to age 65)? (Round your answer to one decimal place.) %

The United States has an aging population, with the number of people aged 65

The median age of the U.S. population in 1980 was 30.0 years. In 1991, the median age was 33.1 years.(a) What does it mean for the median age to rise?A rising median age in a population usually indicates a dying population.A rising median age in a population usually indicates an aging population.    A rising median age in a population usually indicates that people are dying at a younger age.A rising median age in a population usually indicates that the population is becoming younger.A rising median age in a population usually indicates that more babies are being born.(b) Give reasons why the median age could rise. (Select all that apply.)This trend could be observed if there were an increased lifespan and thus a decreased number of deaths.This trend could be observed if there were an increased lifespan and an increased number of deaths.The median age could rise due to an increase in births over time.The median age could rise due to a decrease in births over time.The median age could rise due to an increase in deaths over time.(c) For the median age to rise, is the actual number of children less in 1991 than it was in 1980? Why or why not? (Enter your percentages as a whole number.)Not necessarily but that could be the case. In 1980, % of the population was 30 years old or less. In 1991, % of the population was 33.1 years old or less. On July 1, 1980, the population was about 227.23 million. On July 1, 1991, the population was about 252.98 million. Since half of the population in 1991 was than half of the population in 1980 and the median age in 1991 was greater than the median age in 1980, there could have been children in 1991.

Health care issues are receiving much attention in both academic and political arenas. A sociologist recently conducted a survey of citizens over 60 years of age whose net worth is too high to qualify for Medicaid and have no private health insurance. The ages of 25 uninsured senior citizens were as follows:60   61   62        63        64        65        66        68        68        69        70   73   73  74   75  76  76        81    81        82        86        87      89      90     92 Referring to Table 2,calculate the mean age of the uninsured senior citizens to the nearest hundredth of a year. A. 74.04 years B. 73.95 years C. 74.40 years D. 47.40 years
