None of these (b) Which of the following is the correct formula to compute Test Statistic (TS)?A.135−13015/√36B.130−13515/√36C.135−130225/√36D.130−135225/√36E. None of these (c) What is the value of Test Statistic (TS)? (d) What is the critical value fromCritical Table?( e) What is the p-value ? (f) ConclusionA. RejectH0B.
