The following data show the number of
Chinese citizens who immigrated to the U.S.
Use the data to predict how many Chinese
immigrated to the U.S. during the 1990s.
Decade No. of Chinese Immigrants
1950s 10,000
1960s 35,000
1970s 124,000
1980s 389,00
To predict the number of Chinese immigrants to the U.S. during the 1990s, we can analyze the pattern in the given data.
Let's first observe the increase in the number of Chinese immigrants over each decade:
1950s to 1960s: The number of Chinese immigrants increased by 35,000 - 10,000 = 25,000.
1960s to 1970s: The number of Chinese immigrants increased by 124,000 - 35,000 = 89,000.
1970s to 1980s: The number of Chinese immigrants increased by 389,000 - 124,000 = 265,000.
Based on this pattern, we can assume that the increase in the number of Chinese immigrants during the 1990s would be similar.
To estimate the number of Chinese immigrants in the 1990s, we can project the increase from the previous decade.
1980s to 1990s: Assuming a similar increase as before, we can estimate an increase of approximately 265,000.
To obtain the predicted number of Chinese immigrants in the 1990s, we add this estimated increase to the number of Chinese immigrants in the previous decade:
389,000 (number of Chinese immigrants in the 1980s) + 265,000 (estimated increase in the 1990s) = 654,000
Hence, our prediction is that approximately 654,000 Chinese immigrants immigrated to the U.S. during the 1990s.
