Historically, 52% of Americans have supported stricter gun control. A recent Gallup poll of 1011 showed 495 were in favor of stricter control. Test the claim that the percentage
in favor of stricter control has changed.

a. State the null and alternative hypotheses.

b. Find the z-statistic.

c. Find the p-value.

d. Make a conclusion.

a) 15/7

step-by-step explanation:

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

the correct answer is $7.38

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
