Question: A random sample of final examination grades for a college course follows:

55 85 72 99 48 71 88 70 59 98 80 74 93

85 74 82 90 71 83 60 95 77 84 73 63 72

95 79 51 85 76 81 78 65 75 87 86 70 80

64

Use α = .05 and test to determine whether a normal distribution should be rejected as being representative of the population’s distribution of grades.
