Given the following confidence interval for a population mean, compute the margin of error, E.
10.18<μ<11.90
Margin of error (E) = (Upper bound of CI - Lower bound of CI) / 2
E = (11.90 - 10.18) / 2
E = 1.36
The margin of error is 1.36.
10.18<μ<11.90
E = (11.90 - 10.18) / 2
E = 1.36
The margin of error is 1.36.
