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. b) Find the probability that a randomly selected person in China has a blood pressure of 109.6 mmHg or maore. 0.6417 I ) Find the probability that a randomly selected person in China has a blood pressure of 179.6 mmHg or less. 0.9999 l d) Find the probability that a randomly selected person in China has a blood pressure between 109.6 and 179.6 mmHg. e) Find the probability that randomly selected person in China ha .ure that is at most 70.5 mmHg. 0.0001 I f) Is a blood pressure of 70.5 mmHg unusually low for a randomly selected person in China? Why or why not? v | X yes, since the probability is greater than 0.05 g) What blood pressure do 56% of all people in China have less than? Round your answer to two decimal places in the first box. Put the correct units in the second box. 1256.32 X [mmHg /| o
