The systolic blood pressure (BP) of adults in the USA is nearly normally distributed with a mean of 117 and standard deviation of 17 . Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. (a) Around what percentage of adults in the USA have stage 2 high blood pressure

the percentage of adults have stage 2 high blood pressure is 0.0057

Step-by-step explanation:

The computation of the percentage of adults have stage 2 high blood pressure is shown below;

Given that

mean = 117

Standard deviation = 17

and, the sample is 160

Now based on the above information,

The percentage is

= (Sample - mean) ÷ (standard deviation)

= (160 - 117) ÷ (17)

= 2.529

p(z>2.53) = 0.0057

hence, the percentage of adults have stage 2 high blood pressure is 0.0057

may i see the picture? it would a lot, xox

pretty sure 750 each month!
