Step 1 :Given values are sample mean \(\overline{x} = 25\), sample size \(n = 36\), population standard deviation \(\sigma = 2\), and confidence level of 95% which corresponds to a z-score of \(z = 1.96\).
Step 2 :First, calculate the margin of error using the formula \(z \cdot \frac{\sigma}{\sqrt{n}}\). Substituting the given values, we get \(1.96 \cdot \frac{2}{\sqrt{36}} = 0.653\).
Step 3 :Next, calculate the confidence interval using the formula \(\overline{x} \pm\) margin of error. Substituting the given values, we get \(25 - 0.653 = 24.347\) and \(25 + 0.653 = 25.653\).
Step 4 :Rounding to one decimal place, the confidence interval is from \(24.3\) to \(25.7\).
Step 5 :So, the final answer is: The confidence interval is from \(\boxed{24.3}\) to \(\boxed{25.7}\).
