Given a population where the probability of success is p = 0.30, calculate the probabilities below if a sample of 800 is taken. a. Calculate the probability the proportion of successes in the sample will be less than 0.31. b. What is the probability the proportion of successes in the sample will be greater than 0.33? a. The probability the proportion of successes in the sample will be less than 0.31 is (Round to four decimal places as needed.)
