For one binomial experiment, n1 = 75 binomial trials produced r1 = 45 successes. for a second independent binomial experiment, n2 = 100 binomial trials produced r2 = 70 successes. at the 5% level of significance, test the claim that the probabilities of success for the two binomial experiments differ. compute the pooled probability of success for the two experiments. (round your answer to three decimal places.
