Now consider a random sample of 400 adults. .. a. What is the probability that between 39% and 49% of the sampled adults work during summer vacation? The probability is. (Round to three decimal places as needed.) b. What is the probability that over 60% of the sampled adults work during summer vacation? The probability is (Round to three decimal places as needed.)
