Answer:
Assumptions are not met. Can not make confidence interval.
Step-by-step explanation:
In the General Social Survey, sample size is 1514.
The proportion of those who see themselves social is 
≈ 0.31
To give an 95% confidence interval, we should be able to calculate margin of error of the sample mean, which is given by the formula
M±
where M is the mean of the sample (in the General Social Survey it is 0.31), z is z-score for the 95% confidence level(approx. 1.94), s is the standard deviation of the sample, N is the size of the sample(in this example it is 1514).
Since we don't know the standard deviation of the sample, we cannot give a confidence interval.
I know it's either A B C or D.
Speak Engrish son lol what=what
Answer:
30.5
Step-by-step explanation:
Angle B = Angle D (Alt. Exterior)
61 = 2x
61/2 = 30.5
2n + 20 = -2
20 + 2 = -2n
22 = -2n
22/2 = n
11 = n
