Olaf wants to test to see if Americans can identify more states in the eastern U.S. or the western U.S.The data are below.Calculate the t-statistic, state the critical value, and come to a conclusion about her experiment.You do not have to consider whether a t-test is appropriate or not; assume that it is appropriate.You do, however, need to determine what the appropriate type of t-test is; if you use the wrong type of t-test, you may not receive any credit.You must show ALL your work.Let it be a two-tailed test with (alpha) = .05.By the way, the standard deviation of "East" is 4, and the standard deviation of "West" is 3.
