According to the WHO MONICA Project the mean blood pressure for people in China is 128 mmHg with a standard deviation of 23 mmHg. Assume that blood pressure is normally distributed. Round the probabilities to four decimal places. It is possible with rounding for a probability to be 0.0000. a) State the random variable. Select an answer b) Find the probability that a randomly selected person in China has a blood pressure of 60.1 mmHg or more. c) Find the probability that a randomly selected person in China has a blood pressure of 166.9 mmHg or less. d) Find the probability that a randomly selected person in China has a blood pressure between 60.1 and 166.9 mmHg. e) Find the probability that randomly selected person in China has a blood pressure that is at most 70.5 mmHg
