Two dice were thrown 180 times, and at each throw the number X of sixes was recorded, with the following results. Number of sixes Frequency (x) (f₂) 0 1 2 Total 105 70 5 180 (a) Test the hypothesis that the distribution of X is binomial with probability p of obtaining a six given by p= (b) Explain how the test would be modified when the hypothesis to be tested is that X has a binomial distribution, but p is unspecified.
