Binomial Distribution: Histograms Consider a binomial distribution with n 5 5 trials. Use the probabilities given in Table 2 of the Appendix to make histograms showing the probabilities of r 5 0, 1, 2, 3, 4, and 5 successes for each of the following. Comment on the skewness of each distribution.

(a) The probability of success is p 5 0.50.

(b) The probability of success is p 5 0.25.

(c) The probability of success is p 5 0.75.

(d) What is the relationship between the distributions shown in parts

(b) and (c)?

(e) If the probability of success is p 5 0.73, do you expect the distribution to be skewed to the right or to the left? Why?
