Question

3) The average score on a vocational training test has been known to be 64. Recently, several
changes have been carried out in the programme: the effect of these changes on performance
on the test is unknown. It is therefore desirable to test the null hypothesis that the average score
for all people who will complete the programme will be 64 versus the alternative that it will not
be 64. The following random sample of scores is available.
87. 91. 65. 31. 8. 53, 99, 44, 42, 60, 77, 73, 42, 50
79, 90, 54, 39, 77. 60, 33, 41, 42. 85. 71. 50
Is there evidence that the average score for all people who will complete the programme will be 64?
