(Steps Shown) Determine whether the given conditions justify using the margin of error E=z_alpha / 2 σ / √n when finding a confidence interval


Question: Determine whether the given conditions justify using the margin of error \(\mathrm{E}=\mathrm{z}_{\alpha / 2} \mathrm{\sigma} / \sqrt{\mathrm{n}}\) when finding a confidence interval estimate of the population mean \(\mu\).

The sample size is \(n=216\) and \(\sigma=16\).
