The systolic blood pressure of 18-year-old women is a roughly bell-shaped distribution 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 between 96 mmhg and 144 mmhg?
a. approximately 68%
b. approximately 99.7%
c. approximately 99.99%
d. approximately 95%

C. approximately 99.99%

Step-by-step explanation:

The distribution bell shape is a normal distribution, with mean 120 mmHg and standard deviation 12 mmHg.

The rank between 96 mmHg and 144 mmHg is wider than the rank between mean plus, minus 3 standard deviation (102 mmHg up to 138 mmHg), and this rank is approximately 99.7 %.Therefore  99.99 % includes more closely values in the rank 96 up to 144 mmHg
