According to the WHO MONICA Project the mean systolic blood pressure for people in China is 128 mmHg with a standard deviation of 23 mmHg (Kuulasmaa, Hense & Tolonen, 1998). Assume that systolic blood pressure is normally distributed.

a.) True or False: The random variable x defines the systolic blood pressure of a person in China

b.) Find the probability that a person in China has systolic blood pressure of 135 mmHg or more.

c.) Find the probability that a person in China has systolic blood pressure of 141 mmHg or less.

d.) Find the probability that a person in China has systolic blood pressure between 120 and 125 mmHg.

e.) What systolic blood pressure do 90% of all people in China have less than?
