A cоmpаny wаnted tо cоmpаre the performance of its call center employees in two independent centers (West and East). The random sample selected from the West Center had 225 employees with a mean number of cases resolved of 12 and a sample SD of 1.5. The random sample chosen from East Center had 400 employees with a mean number of cases resolved of 11.7 and a sample SD of 1.8.a) State the hypotheses for the test. (1 point)b) Calculate the test statistic and p-value. Your test statistic should be either a z-value or a t-value, whichever is appropriate for the problem. You should support the selection of the test based on assumptions. (4 points )c) Reach your conclusion for the test at the 5% significance level. (1 point)d) Is it possible to conclude causation or association between the center and the number of cases resolved? Explain (Election=1 point, support=1 point)
