- Suppose classmates who graduated in 2004 compared their median incomes ten years later. The bar graph displays the median income, in thousands of dollars, for each classmate during the time intervals from 2005‑2009 and 2010‑2014. For the individual with the largest dollar value increase in median income over the two time intervals, determine the amount of increase.arrow_forwardComplete the following table: LU 6-2(3) 6–50. 6–51.arrow_forwardQ. Table gives data on gold prices, the Consumer Price Index (CPI), and the New York Stock Exchange (NYSE) Index for the United States for the period 1974 –2006. The NYSE Index includes most of the stocks listed on the NYSE, some 1500-plus. a. Plot in the same scattergram gold prices, CPI, and the NYSE Index. b. An investment is supposed to be a hedge against inflation if its price and /or rate of return at least keeps pace with inflation. To test this hypothesis, suppose you decide to fit the following model, assuming the scatterplot in (a) suggests that this is appropriate: Gold pricet = β1 + β2 CPIt + ut NYSE indext = β1 + β2 CPIt + ut Note that if beta2 = 1 the response exactly grows with CPI Thank you!arrow_forward

Determine if the following graphs represent a linear, quadratic, or exponential relationship.arrow_forwardGraph. 1. 2. 1 A. -6-5 -4 -3 -3, -5. -6arrow_forwardThe line graphs in Figure show the percentages of marriages ending in divorce based on the wife’s age at marriage.Here are two mathematical models that approximate the data displayed by the line graphs:In each model, the variable n is the number of years after marriage and the variable d is the percentage of marriages ending in divorce.a. Use the appropriate formula to determine the percentage of marriagesending in divorce after 10 years when the wife is over 25 at the time ofmarriage.b. Use the appropriate line graph in Figure to determine the percentageof marriages ending in divorce after 10 years when the wife is over 25 at the time of marriage.c. Does the value given by the mathematical model underestimate or overestimate the actual percentage of marriages ending in divorce after10 years as shown by the graph? By how much?arrow_forward
- In 2011, home prices and mortgage rates fell so far that in a number of cities the monthly cost of owning a home was less expensive than renting. The following data show the average asking rent and the monthly mortgage on the median-priced home (including taxes and insurance) for 10 cities where the average monthly mortgage payment was less than the average asking rent (The Wall Street Journal, November 26–27, 2011). 7.
