Question

The distribution of systolick blood pressure of 19-year old women is approximantely bell shaped with a mean of 120 mmHg and standard deviation of 12 mmHg.

What percentage of 19 year old women have a systolic blood pressure less than 144 mmHg? Draw  a curve, label the horizontal axix and the curve itself with the appropriate Empirical Rule values as shown and shade the specified area.

 

Approximate percentage: 

What systolic blood pressure value is 1.4 standard deviation Below the mean?

How many standard deviations from the mean is a systolic blood pressure value of 148?
