Suppose we are sampling from a population that is known to be normal with a standard deviation of $\sigma =12$. However, the mean $\mu$ is unknown, so we will need to estimate it using our sample mean. A. For a sample mean $\left({\mathrm{X}}_{\text{bat }}\right)=26$ and a sample size $\mathrm{N}=49$, compute a $95\%$ confidence interval for $\mu$. (Show the process you used to determine the CI bounds.) B. In your own words, explain the meaning of the confidence interval you have found.
