-0.02

Question

Express the confidence interval in the form of $\hat{p}$ ± E.
-0.02 < p < 0.48 
A) $\hat { p } = 0.23 \pm 0.5$
B) $\hat { p } = 0.25 - 0.23$
C) $\hat { p } = 0.25 \pm 0.23$
D) $\hat { p } = 0.25 \pm 0.5$

Quizplus · Accepted Answer

The confidence interval is given as 0.02 < p < 0.48. The midpoint ($\hat{p}$) is (0.02 + 0.48) / 2 = 0.25, and the margin of error (E) is (0.48 - 0.02) / 2 = 0.23. Therefore, the confidence interval can be expressed as $\hat{p} = 0.25 \pm 0.23$.
