Answer: 83

Step-by-step explanation:

The confidence interval for population mean is given by :-

$\overline{x}\pm E$

Given : The student obtained the following 95% confidence interval (in grams) for the population mean, (862,1028).

Here,

Lower limit of the confidence interval : $\overline{x}-E=862$ (1)

Upper limit of the confidence interval : $\overline{x}+E=1028$ (2)

Subtracting (1) from (2) , we get

$2E=166\\\\\Rightarrow\ E=\dfrac{166}{2}=83$

Hence, the margin of error = 83
