Government agencies keep data about the income distribution of the population. The Garcia family and Wood family live in a county with 6000 families. The Garcia family's income is at the 38 percentile. The Wood family's income is at the 73 th percentile. (If necessary, consult a list of formulas.) (a) Which of the following must be true about the Garcia family's and the Wood family's incomes? Both the Garcia family and the Wood family earn more than the median income. Both the Garcia family and the Wood family earn less than the median income. O The Wood family earns more than the Garcia family. O The Garcia family earns more than the Wood family. (b) Which of the following must be true about the Garcia family's income? O About 38% of the families in their county earn less than the Garcia family. O The Garcia family earns about 38% of the highest income in their county. O The Garcia family's income is in the top half of incomes in their county. O The Garcia family earns $38,000.
FARM POPULATION Consider the percent of the United States population which lived on farms during the years 1880-1990. Year Percent 1880 43.8% 1890 42.3% 1900 41.9% 1910 34.9% 1920 3.1% 1930 24.9% 1940 23.2% 1950 15.3% 1960 8.7% 1970 4.8% 1980 2.7% 1990 1.9% 1. Using technology, calculate the average rate of change per year. You may, for example, make a table in a spreadsheet with Year, Percent of Population, and Average Rate of Change, as three columns. What are the independent and independent variables? 2. Using technology, create a plot of Percentage vs Year. Does the data appear to be linear? Explain. 3. Using technology, construct a linear trendline and determine the R2 value. What is the trendline equation? What is the slope, including units? What is the R2 value? Is there a strong or weak correlation? 4. Using the trendline formula, calculate algebraically the date when 100% of the population lived on a farm? Explain in the context of the problem. 5. Using the trendline…
