Assume that blood pressure readings are normally distributed with u=120 and o=8 A blood pressure reading of 145 or more may require medical attention. What percentage of people have a blood pressure reading greater than 145?
---
z(145) = (145-120)/8 = 25/8
---
P(x > 145) = P(z > 27/8) = 0.0008891.. = 0.08891%
