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. What is the random variable in this problem? Select an answer In the remaining questions, round all probabilities to four decimal places. It is possible that, after rounding, your answer may be zero. Read your calculator carefully. Find the probability that a randomly selected person in China has a blood pressure of 95.9 mmHg or more. Find the probability that a randomly selected person in China has a blood pressure of 97.1 mmHg or less. Find the probability that a randomly selected person in China has a blood pressure between 95.9 and 97.1 mmHg. Find the probability that randomly selected person in China has a blood pressure that is at most 70.5 mmHg-
