Given the following contingency table, conduct a test for independence at the 1% significance level. (You may find it useful to reference the appropriate table: chi-square table or F table) Variable A Variable B 1 2 1 33 50 2 45 50 a. Choose the null and alternative hypotheses. multiple choice 1 H0: The two variables are independent.; HA: The two variables are dependent. Correct H0: The two variables are dependent.; HA: The two variables are independent. b. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)
