Quizplus · Accepted Answer

The distribution is skewed to the left since most of the values are concentrated on the higher end and tail off towards the left. It is not a binomial distribution as it does not have a fixed number of trials or a constant probability of success. It also is not a normal distribution since it is discrete and not continuous. There are not multiple peaks, so it is not bimodal.
