Question 977838: The systolic blood pressures of 40 women have a mean of 110.8 mm Hg and a standard deviation of 17.1 mm Hg. The highest systolic blood pressure measurement in this sample is 181 mm Hg. In this context, is a systolic blood pressure of 181 mm Hg "unusual"? Why or why not? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Find the z score.
Typically unusual readings are z scores greater than 2 and very unusual are z scores greater than 3.
So yes, it's highly unusual.
