The systolic blood pressure of 18- year- old women is normally distributed with a mean of 120 mmHg and a standard deviation of 12 mmHg. What percentage of 18- year- old women have a systolic blood pressure that lies within 3 standard deviations to either side of the mean?

99.7% of of 18- year- old women have a systolic blood pressure that lies within 3 standard deviations to either side of the mean

Step-by-step explanation:

We would apply the standard deviation rule. The Standard Deviation Rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated below

68% of data falls within the first standard deviation from the mean.

95% fall within two standard deviations.

99.7% fall within three standard deviations.

From the information given, the mean is 120 mmHg and the standard deviation is 12 mmHg.

Therefore,

99.7% of of 18- year- old women have a systolic blood pressure that lies within 3 standard deviations to either side of the mean.

99.74%

Step-by-step explanation:

Using empirical rule (68 - 95 - 99.7)

Approximately, 99.7% data falls in 3 standard deviation of the mean.

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
