# Question: A Use a computer or random number table to generate

a. Use a computer (or random number table) to generate a random sample of 25 observations drawn from the following discrete probability distribution.

Compare the resulting data to your expectations.

b. Form a relative frequency distribution of the random data.

c. Construct a probability histogram of the given distribution and a relative frequency histogram of the observed data using class midpoints of 1, 2, 3, 4, and 5.

d. Compare the observed data with the theoretical distribution. Describe your conclusions.

e. Repeat parts a through d several times with n _ 25 Describe the variability you observe between samples.

f. Repeat parts a through d several times with n _ 250 Describe the variability you see between samples of this much larger size.
