MOE=\pm \ 1.41

Step-by-step explanation:

-Given that \sigma=1.91, n=7

-We determine the z-value corresponding to the 95% confidence level:

z_{\alpha/2}=z_{0.025}=1.96

-The margin of error is the degree of error from the real value and is calculated as follows:

MOE=\pm z_{\alpha/2} (\frac{\sigma}{\sqrt{n}})\\\\=\pm z_{0.025}\times\frac{\sigma}{\sqrt{n}}\\\\=\pm 1.96\times \frac{1.91}{\sqrt{7}}\\\\=\pm 1.41

Hence, the margin of error is \pm 1.41
