A) $\bar { x } \pm 2.3$
B) $\bar { x } \pm 4.6$
C) $\bar { x } \pm 4.508$
D) $\bar { x } \pm 6.9$

Question

Quizplus · Accepted Answer

The margin of error is the amount added and subtracted from the sample mean ($\bar{x}$) to create the interval estimate. Therefore, the interval estimate is $\bar{x} \pm 4.6$.
