Question
20. A researcher selects a sample of 1000 people to investigate the relationship between ethnicity (Caucasian, African-American, Hispanic/Latino and Other) and registering to vote (registered to vote, not registered to vote). If the researcher obtains a Chi2 = 8.37, what is the appropriate statistical decision for the test? Assume p < .05.
A. Reject the null hypothesis and conclude that there is no significant relationship between ethnicity and registering to vote. B. Reject the null hypothesis and conclude that there is a significant relationship between ethnicity and registering to vote. C. Fail to reject the null hypothesis and conclude that there is a significant relationship between ethnicity and registering to vote. D. Fail to reject the null hypothesis and conclude that there is no significant relationship between ethnicity and registering to vote.Explanation / Answer
As P < 0.05, then that is a small P value, so we reject Ho.
Hence, the relationship is significant,
