A person with normal blood pressure has a diastolic measurement of 75 mmHg, and a standard deviation of 4.5 mmHg. Assume the population data in this scenario is normally distributed.

a.
What is the probability that a randomly selected person with normal blood pressure will get
a diastolic result
of over 80 mmHg, indicating the possibility of prehypertension?

b.
If a patient takes his blood pressure every day for a
week, what is the probability of getting
an average diastolic blood pressure
result of over 80 mmHg, assuming the patient has normal blood pressure? What can we conclude about such as result?
