A) Do not reject the hypothesis that the sequence is random, because the test value 4 is between the critical values 3 and 11.
B) Do not reject the hypothesis that the sequence is random, because the test value 3 is between the critical values 3 and 10.
C) Do not reject the hypothesis that the sequence is random, because the test value 5 is outside the critical values 3 and 12.
D) Reject the hypothesis that the sequence is random, because the test value 3 is between the critical values 3 and 11.
