7) if the systolic blood pressure is normally distributed in the population with a mean=120, sd=20, x~n(120, 20) what is the probability of a random person having systolic blood pressure of 130 or greater (hint: calculate the z score, then find the probability in the right tail)

Step-by-step explanation:

Given that the systolic blood pressure is normally distributed in the population with a mean=120, SD=20.

the probability of a random person having systolic blood pressure of 130 or greater

Convert 130 to Z score as

Required probability=

P(Z\geq  0.5) =

=0.5-0.1915

=0.3085

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
