Given:

With a confidence level of 95%, out of 280 trials, there were 123 successes. What is the margin of error?

Inference App
[Symb]
Method: Confidence interval
Type: Z-Int: 1 pi

[Num]
x:123
n:280
c:0.95

[Plot] NOTE: Confidence interval is shown, the margin of error is not shown, typically reported as the center value ± margin of error. Can this be shown on the plot somehow?
