Answer:
And the best option for this case would be:
A. 0.050 to 0.112.
Step-by-step explanation:
Data given
represent the real population proportion of who support the cnadite for the northern half state
represent the estimated proportion of who support the candidate for the northern half state
is the sample size required the northern half state
represent the real population proportion of who support the candidate for the southern half state
represent the estimated proportion of people who support the candidate for the southern half state
is the sample size for the northern half state
represent the critical value
The confidence interval for the difference of two proportions would be given by this formula
For the 95% confidence interval the value of
and
, with that value we can find the quantile in the normal standard distribution and we got.
Replacing into the formula we got:
And the best option for this case would be:
A. 0.050 to 0.112.
Ok the correct answer is.........17.928666
Answer:
none
Step-by-step explanation:
(8-5)=3
8-5÷23
=179/23
120+10+5=135
I don't know if all you're supposed to do is add or not... so i may be wrong....
Answer:
25.5
Step-by-step explanation:
first find angle E.
remember, all angles in a triangle always add up to 180 degrees.
E = 180 - 90 - 20 = 70 degrees
now we use the law of sines.
ED/sin(20) = DC/sin(70) = EC/sin(D)
EC = x
sin(D) = sin(90) = 1
24/sin(70) = x/1 = x
x = 25.5
