Look at the histogram of probabilities in the binomial distribution template [Binomial.xls] for the case n = 5 and p = 0.6.

a. Is this distribution symmetric or skewed? Now, increase the value of n to 10, 15, 20, . . . Is the distribution becoming more symmetric or more skewed? Make a formal statement about what happens to the distribution’s shape when n increases.

b. With n = 5, change the p value to 0.1, 0.2, . . . Observe particularly the case of p = 0.5. Make a formal statement about how the skewness of the distribution changes with p
