In 2008, the centers for disease control and prevention reported that 34% of adults in the united states are obese. a country health service planning a new awareness campaign polls a random sample of 750 adults living there. in this sample, 228 people were found to be obese based on their answers to a health questionnaire. do these response provide strong evidence that the 34% figure is not accurate for this region?

No, these response does not provide strong evidence that the 34% figure is not accurate for this region.

Step-by-step explanation:

Since we have given that

p = 0.34

x= 228

n = 750

So,

So, hypothesis would be

So, test statistic value would be

At 95% confidence , z = 1.96

So, 1.96>-4.293.

So, we accept the null hypothesis.

No, these response does not provide strong evidence that the 34% figure is not accurate for this region.

20%

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
