Stomach pH values fluctuate between 1.5 and 3.5. The researchers expect that in healthy patients in their study, this will also be the case, and that approximately 50% of the healthy patients will have a stomach pH below 2.5. After collecting data, they find that 30 of 87 healthy patients, or 34.48%, have stomach pH levels below 2.5. Use this information to answer 1. Assume that the probability that a healthy patient has a stomach pH below 2.5 is 50%....
