Explanation of Solution
Given information:
Diastolic pressure value,
Mean,
Standard deviation,
Calculations:
Calculate the Z − score,
Use normal probability table in the appendix, to find the corresponding probability.
See the row that starts with 1.5 and the column that starts with .00 of the standard normal probability table for
Therefore,
Around 6.68% of the adults have a diastolic pressure exceeding 100, that has been classified as very high blood pressure.
