For a binomial distribution with n = 15 as p changes from. 50 toward. 05 the distribution will__________?
Correct answer: A. Become more positively skewed
- A. Become more positively skewed
- B. Become more negatively skewed
- C. Become symmetrical
- D. All of the above.
Explanation
The binomial skewness is determined by q − p: at p = 0.50 it is symmetric, but as p falls below 0.50, q becomes larger and the distribution develops positive skewness. Therefore, it becomes more positively skewed.
