Cаrlsоn Schооl of Mаnаgement recently changed its logo. Given the rating of the new logo, you decide to convince the school to review its decision to change the logo. To do so, you decide to run an A/B test to determine whether or not to go back to the old logo (Logo 1) or keep the new one (Logo 2). You selected two groups G1 and G2, to run the A/B experiment. Group G1 rated Logo 1 and Group G2 rated Logo 2. You can consider the rating to be on a scale of 1-10. Assuming a significance level of 0.01. Clearly define the null hypothesis and the alternative hypothesis for this A/B test. Identify the independent variable and the dependent variable. Would the extraneous variables be addressed if G1 and G2 were selected from among first year students, faculty, and staff at Carlson? Justify your answer, Can you use a two-sample t-test assuming equal variances? Justify your answer.
