A group of 600 students were randomly assigned to 6 different educational programs (E1, E2, E3, E4, E5, E6), with the frequencies shown below. Is it appropriate to conclude that the assignment distribution was truly random?
Program E1: 87 students
Program E2: 96 students
Program E3: 108 students
Program E4: 89 students
Program E5: 122 students
Program E6: 98 students
The randomness can be checked by the frequency test, was very basic: checking to make sure that there were roughly the same number of 0s, 1s, 2s, 3s, etc. Here, the frequencies are not same. Hence, the assignment distribution is not truly random.
