Two placement exams are available that students can take to determine which math class they should begin with in their freshman year. It is believed that there is no difference in the mean scores that would be received for the two tests.
 
  To test this using a 0.05 level of significance, a randomly selected group of students took both tests and had their scores recorded. The following data were obtained:Student Test A Test B1 78 822 86 743 74 794 72 935 75 806 68 827 77 99Based on these data, the test statistic is approximately t = -1.892.
