19. A 55-year-old male patient of a local doctor was diagnosed with high blood pressure. He was put on blood pressure medication and was able to somewhat control his high blood pressure. In order to make sure that the medication was working effectively he was required to monitor his blood pressure three times every day. The probability distribution of his daily systolic blood pressure readings followed a normal distribution with a mean of 130 and a standard deviation of 6. Find the probability that the mean of his three readings exceeds 140, which is considered problematic. Here are two different Minitab outputs (Output A and Output B). You can use one of them (the correct one!) to answer this question or you can do the problem out. * Output A: Cumulative Distribution Function Normal with mean = 130 and standard deviation = 6 P( X
