A Gallup Poll released in December 2010 asked 1019 adults living in the Continental U.S. about their belief in the origin of humans. These results, along with results from a more comprehensive poll from 2001 (that we will assume to be exactly accurate), are summarized in the table below:
Response | Year: 2010 | Year: 2001 |
---|---|---|
Humans Evolved with God guiding (1) | 38% | 37% |
Humans evolved but God had no part in the 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 in each response category as well as the expected number, assuming that the population follows the 2001 distribution. (please round to the nearest whole number)
Response | Observed 2010 | Expected 2010 |
---|---|---|
Humans Evolved with God guiding (1) | ||
Humans evolved but God had no part in the process (2) | ||
God created humans in present form (3) | ||
Other / No opinion (4) |
Conduct a chi-square test and state your conclusion.
The value of the test statistic is: .... (please round to two decimal places)
The p-value for this test is: .... (please round to four decimal places; you can use CHISQ.DIST Excel function)
State the conclusion.
