Asurvey of a random sample of 1,500 young americans found that 87% had earned their high school diploma. based on these results, the 95% confidence interval for the proportion of young americans who have earned their high school diploma is (0.853,0.887) what is the margin of error for this confidence interval?

0.017

Step-by-step explanation:

The confidence interval for population proportion p is given by :-

, where E is the margin of error.

Given : The proportion of the sample of young Americans earned their high school diploma :

The 95% confidence interval for the proportion of young Americans who have earned their high school diploma is (0.853,0.887) .

i.e.

Subtract equation (1) from (2) , we get

Hence, the margin of error for this confidence interval =0.017

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
