95% have a systolic blood pressure between 109 and 141
Empirical rule states that for a normal distribution, 68% are within one standard deviation from the mean, 95% are within two standard deviation from the mean and 99.7% are within three standard deviation from the mean.
Given that mean (μ) = 125, standard deviation (σ) = 8.
68% are within one standard deviation = μ ± σ = 125 ± 8 = (117, 133)
95% are within two standard deviation = μ ± 2σ = 125 ± 2*8 = (109, 141)
95% have a systolic blood pressure between 109 and 141
