anonymous one year ago Express the confidence intervals (0.026, 0.124) in the form of p - E < p < p + E.

what is P and E?

$\frac{(p-E)+(p+E)}{2}=p$ where $$p$$ is the midpoint of a confidence interval. You're explicitly given that $$p-E=0.026$$ and $$p+E=0.124$$. You can easily find $$p$$ then $$E$$ from here. Oh, and the interval should be in the form $$p-E<\hat{p}<p+E$$, where $$\hat{p}$$ is whatever statistic is being estimated.
