Answer:
0.4207 is the probability that the blood pressure is less than 97.
Explanation:
We are given the following information in the question:
Mean, μ = 100
Standard Deviation, σ = 15
We are given that the distribution of blood pressure is a bell shaped distribution that is a normal distribution.
Formula:
P(blood pressure is less than 97)
P(x < 97)
Calculation the value from standard normal z table, we have,
0.4207 is the probability that the blood pressure is less than 97.
