So the union of A, B, and C does not constitute the entire sample space.
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.
