Question

the table below lists the percent of a countrys population that is foreign-born for selected years.

year	1930	1940	1950	1960	1970	1980	1990	2000	2008

answer parts a through e.
(c) plot the data together with f in the same window. how well does f model the percent of the population that is foreign-born?
choose the correct graph below.
a.
b.
c.
d.
0,80,10 by 0,15,3

Explanation:

First, analyze the trend of the data: the percent of foreign-born population decreases from 1930 (11.5) to 1970 (4.4), then increases through 2008 (12.6), forming a U-shaped curve. Now match this to the graphs:

• Graphs C and D are downward-opening curves (peak then decline), which do not match the data trend.
• Graph A: the data points do not align with the U-shape's upward phase correctly.
• Graph B: the data points follow the U-shaped trend (fall to a minimum then rise) that matches the given year-percent data.

Answer:

B. <The graph with a U-shaped curve where data points fall to a minimum then rise, matching the trend of decreasing then increasing foreign-born population percent>
