Question:

The systolic blood pressure of adults in a large city is nearly normally distributed with a mean of 117 and standard deviatio
The systolic blood pressure of adults in a large city is nearly normally distributed with a mean of 117 and standard deviation of 19. 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? Give your answer rounded to two decimal places. % b. If you sampled 2000 people, how many would you expect to have BP> 1607 Give your answer to the nearest person. people c. Stage 1 high BP is specified as systolic BP between 140 and 160. What percentage of adults in the US qualify for stage 12 % d. Your doctor tells you you are in the 30th percentile for blood pressure among US adults. What is your systolic BP? Round to 2 decimal places. lbs

Answers

From the given information,

Mean=117

Sd=19

By using calculator,

The required correct answers are,

a. P(X>160)= 1.18 %

b. 24 people

c. P(140<X<160)= 10.12 %

d. 107.04 lbs

1. An elecron's mass is 0.511 MeV/c^2 , while a proton's mass is 938.3 MeV/c^2 , which is about (938.5 MeV/c^2 ) / (0.511 MeV/c^2 ) ~ 1800 times larger. So a proton traveling at a low speed of 1 m/s would have roughly the same momentum as an electron traveling at 1800 m/s. But since neither ...
