Answer: (92, 128)
Step-by-step explanation:
According to the Empirical rule,
If the population is normallly distributed, then 95% of the population lies within 2 standard deviations from the mean.
Given: Mean = 110
Standard deviation = 9
The interval of systolic blood pressures represent the middle 95% of males:
(110-2(9), 110+2(9))
= (110-18, 110+18)
= (92, 128)
Hence, the interval of systolic blood pressures that represent the middle 95 % of males = (92, 128)
