According to Census data, in 1950 the population of the U.S. amounted to 151.3 million persons,
and 13.4% of them were living in the West. In 2000, the population was 281.4 million, and
22.5% of them were living in the West. Is the difference in % practically significant?
statistically significant? Or do these questions make sense? Explain briefly.
Solution
population in west in 1950 - 20.72 million
population in west in 2000- 63.315 million
this is both practically & statistically signiicant becoz this shows the change in population in 50
years in west . this change can be due to more development in west or other reasons . practically
it is significant becoz population increases in the areas where more development is there &
statically it shows the % change in the population in 50 years..
