It is said that the normal mean systolic blood pressure is 120 mm Hg with astandard deviation of 18 mm Hg. A random sample of 40 persons were taken andwas observed to have a mean systolic blood pressure of 135 mm Hg. Can weconclude that the sys-tolic blood pressure of the sample is higher than that of thepopulation at 5% level of significance?

i think that you should ask google for the answer to that problem because if we don't know it google does

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
