Answer:
99.7%
Step-by-step explanation:
According to the Empirical Rule:
- 68% of data in a normal distribution are ±1σ from the mean μ
- 95% of data in a normal distribution are ±2σ from the mean μ
- 99.7% of data in a normal distribution are ±3σ from the mean μ
By calculating the z-score of each observed value, we can determine how many standard deviations these observed values are from the mean:
Clearly, we can see that 99.7% of males in the town have a systolic blood pressure between 99 and 141 by the Empirical Rule.
