please help me solve this problem
ANSWER: 0.519 ± 0.57
Why???
p = EXPECTED VALUE which is always half-way in the confidence interval. Half-way is computed between 1.089 and -0.051 [0.519].
E = ERROR OF THE ESTIMATE and is half the width of the confidence interval. Half of the confidence interval = 1/2 * (1.089 - (-0.051)) [0.57].
