Below is a contingency table showing the responses in a sample survey in which 200 economists were asked to report their level of confidence that the economy would improve significantly over the next 12 months.The professional affiliation (university or industry) of the economists is also shown. You are conducting a chi-square test to determine whether "confidence in the economy" is independent of "professional affiliation," at a significance level of 0.05.The chi-square statistic for the test turns out to be 1.042.What is your conclusion?
A)The two factors are not independent.
B)Do not reject the independence null hypothesis.
C)Reject the independence null hypothesis
D)The test results are inconclusive; a larger sample is needed.
E)The economists are evenly split in their responses.
