According to Census data, in 1960 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.  Select all statements are true. a. The two populations from 1960 and 2000 are dependent, because people who lived in the West in 1960 were much more likely to live in the West in 2000 too. b. The difference of the population percentage living in the west between 1960 and 2000 is statistically significant. c. The concept of statistical significance does not apply here, because the percentages are from the whole populations. d. The geographic distribution of the US population has shifted to the West from 1960 to 2000 and the difference is practically significant.
