Is there а difference in perfоrmаnce when students tаke exams alоne оr in a class setting. Eleven students were given two tests of equal difficulty? They took one test in a solitary room and they took the other in a room filled with other students. The results are shown below. Alone 88 74 94 65 75 79 86 81 70 77 90 Group 86 78 97 69 75 77 90 83 78 72 95 Assume the distribution of the differences is normal. What can be concluded at the 0.01 level of significance? (d = alone score  - group score)   A.  H0: d [eq] 0       Ha: d [neq] 0 B.  Test statistic: [response2] C.  p-Value = [response3] D.  Decision: [response4] E.  Conclusion: There is [response5] evidence to make the conclusion that the population mean exam score differs based on whether students take the exam alone or around others.
