For one binomial experiment, n, = 75 binomial trials produced r, = 30 successes. For a second independent binomial experiment,
n, = 100 binomial trials produced r, = 50 successes. At the 5% level of significance, test the claim that the probabilities of success

for the two binomial experiments differ.
