Question

For males in a certain town, the systolic blood pressure is normally distributed with a mean of 125 and a standard deviation of 10. Using the empirical rule, determine the interval of systolic blood pressures that represent the middle 99.7% of males.​

Answer 1

Answer is g =93 to 147

Answer 2

G= 93 to 147

Explanation:

From the question we are told that

Mean x = 120

Standard deviation o = 9

Percentage for men =99.75%

Generally the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean

Standard deviation n= 9

Mean x= 120

Generally the interval of systolic blood pressure for middle 99.7 of male G is mathematically given as

G = mean + 3 * o

G = 120 + 3 * 9

G = 93 to 147
