$2|x-1|-4= -2\\\\
2|x-1|=2\\\\
|x-1|=1\\\\
x-1=1 \vee x-1=-1\\\\
x=2 \vee x=0\\\\

Option c

Step-by-step explanation:

--The large-sample confidence interval

formula for proportions is valid if np ≥ 15 and n(1-p) ≥ 15. The large sample confidence

interval only contain the true value a certain percentage of the time. A 95% CI will contain the

value 95% of the time. You add 2 successes and 2 failures.
