Jim's systolic blood pressure is a random variable with a mean of 147 mmHg and a standard deviation of 10 mmHg. For Jim's age group, 140 is the threshold for high blood pressure. Assume the data given follow the normal probability distribution. (a) If Jim's systolic blood pressure is taken at a randomly chosen moment, what is the probability that it will be 139 or less? (Round your z-value to 2 decimal places. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.) Probability (b) If Jim's systolic blood pressure is taken at a randomly chosen moment, what is the probability that it will be 178 or more? (Round your z-value to 2 decimal places. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.) Probability (c) If Jim's systolic blood pressure is taken at a randomly chosen moment, what is the probability that it will be between 126 and 172? (Round your z-value to 2 decimal places. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.) Probability
