A Gallup Poll released in December 2010 asked 1019 adults livingin the Continental U.S. about their belief in the origin of humans.These results, along with results from a more comprehensive pollfrom 2001 (that we will assume to be exactly accurate), aresummarized in the table below:
Response | Year: 2010 | Year: 2001 |
---|
Humans Evolved with God guiding(1) | 38% | 37% |
Humans evolved but God had no part inthe process (2) | 16% | 12% |
God created humans in present form(3) | 40% | 45% |
Other / No opinion (4) | 6% | 6% |
Calculate the actual number of respondents in 2010 that fall ineach response category as well as the expected number, assumingthat the population follows the 2001 distribution. (pleaseround to the nearest whole number)
