Jim's systolic blood pressure is a random variable with a mean of 140 mmHg and a standard deviation of 16 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 130 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.)

(b) If Jim's systolic blood pressure is taken at a randomly chosen moment, what is the probability that it will be 166 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.)

(c) If Jim's systolic blood pressure is taken at a randomly chosen moment, what is the probability that it will be between 117 and 160? (Round your z-value to 2 decimal places. Use Appendix C-2 to find probabilities. Round your final answer to 4 decimal places.)
