Suppose that 85% of all business managers are willing to switch companies if offered a salary increase of 20%. If a headhunter randomly contacts a simple random sample of 51 managers, what is the probability that the proportion willing to switch companies if offered a higher salary is between 0.9115 and 0.946? (Choose the best/closest answer to account for minor rounding)

Hint: For maximum accuracy, you should use technology rather than the Normal Tables to compute this probability.
