Question:

An observed frequency is as follows:
Number of successes
0
1
2
3
Frequency
89
133
52
26
a. Assuming a binomial with n = 3 and p = 1/3, use the binomial probability formula to find the probability corresponding to each category of the table.
b. Using the probabilities found in part (a), find the expected frequency for each category.
c. Use a 0.05 level of significance to test the claim that the observed frequencies fit a binomial for which n = 3 and p = 1/3.
