Consider a normally distributed population with unknown mean $\mu$ and standard deviation $\sigma = 1.5$ .

From this population, a sample of size $n=77$ is drawn. The mean of the sample is $\bar{X}=10.6$ .

Construct the $95\%$ confidence interval for the population mean $\mu$ on the basis of this sample. Round your answers to three decimal places.

$CI_{\mu,\,95\%}=\, ($
