A study conducted in 2007 by The Baylor DepartmentSociology asked the following question: ”Please indicateyour level of agreement with the following statementabout science: Humans evolved from other primates overmillions of years.” The researcher summarized the datain a table categorizing the responses by level of Beliefin Evolution and the Age group of the respondent. TheP-value for a chi-square test of independence based was0.025. Which statement correctly interprets this P-value?A) The probability that the variables Age and Belief inEvolution are independent is 0.025.B) The probability that the variables Age and Belief inEvolution are independent is 0.975.C) Given the data that were observed, the probabilitythat the variables Age and Belief in Evolution areindependent is 0.025.D) If Belief in Evolution is independent of Age, theprobability of seeing results at least this extreme isonly 0.025.E) If there is an association between Belief in Evolutionand Age, the probability of seeing results at least thisextreme is only 0.025.

Sociology asked the following question: ”Please indicate
your level of agreement with the following statement
about science: Humans evolved from other primates over
millions of years.” The researcher summarized the data
in a table categorizing the responses by level of Belief
in Evolution and the Age group of the respondent. The
P-value for a chi-square test of independence based was
0.025. Which statement correctly interprets this P-value?
A) The probability that the variables Age and Belief in
Evolution are independent is 0.025.
B) The probability that the variables Age and Belief in
Evolution are independent is 0.975.C) Given the data that were observed, the probability
that the variables Age and Belief in Evolution are
independent is 0.025.
D) If Belief in Evolution is independent of Age, the
probability of seeing results at least this extreme is
only 0.025.
E) If there is an association between Belief in Evolution
and Age, the probability of seeing results at least this
extreme is only 0.025.
