  • You need to compute the probability of 5 or fewer successes for a binomial experiment with...

    You need to compute the probability of 5 or fewer successes for a binomial experiment with 10 trials. The probability of success on a single trial is 0.57. Since this probability of success is not in the table, you decide to use the normal approximation to the binomial. Is this an appropriate strategy? Explain. No, np < 5. Yes, np < 5.     Yes, np > 5. No, np > 5.
