Please help! Thanks!: If a 95% confidence interval was being calculated using the following expression:

Roman55 [17]

The confidence interval can be calculated from the margin of error, and vice versa,

The margin of error of the confidence interval is 2.156

The confidence interval is given as:

$\mathbf{CI = 3.2 \pm 1.96 \cdot 1.1}$

The formula of confidence interval is:

$\mathbf{CI = \bar x\pm E}$

Where E represents the margin of error.

So, by comparison:

$\mathbf{E = 1.96 \cdot 1.1}$

Multiply

$\mathbf{E = 2.156}$

Hence, the margin of error of the confidence interval is 2.156
