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 who came to the U.S. during the 1990s, we can analyze the trend in the number of Chinese immigrants over the given decades.
From the given data, we can see that the number of Chinese immigrants is increasing rapidly with each passing decade. Therefore, we can assume that this trend will continue into the 1990s.
To make a prediction, we can calculate the average increase between each decade and then apply that average increase to the number of Chinese immigrants in the previous decade (1980s).
Let's calculate the average increase in the number of Chinese immigrants between each decade:
Increase from 1950s to 1960s: 35,000 - 10,000 = 25,000
Increase from 1960s to 1970s: 124,000 - 35,000 = 89,000
Increase from 1970s to 1980s: 389,000 - 124,000 = 265,000
Next, we'll calculate the average increase:
Average increase = (25,000 + 89,000 + 265,000) / 3 = 126,333.33
To predict the number of Chinese immigrants in the 1990s, we'll add this average increase to the number of Chinese immigrants in the previous decade (1980s).
Prediction for the 1990s = 389,000 + 126,333.33 = 515,333.33
Therefore, based on the given data and the trend observed, we can predict that approximately 515,333 Chinese immigrants came to the U.S. during the 1990s.
