Quizplus · Accepted Answer

A Poisson distribution is often positively skewed, meaning that the tail of the distribution extends further to the right than to the left. This is because the distribution is bounded on the left by zero, but can extend without limit to the right. A value of .60 for the parameter lambda indicates a moderate or high rate of occurrence, which further increases the likelihood of a positively skewed distribution. Therefore, the answer is C) positively skewed distribution (skewed to the right).
