Q1. Use the estimation method to calculate and interpret a confidence interval.(3 points)

Suppose we are sampling from a population that is known to be normal with a standard deviation of = 5. However, the mean is unknown, so we will need to estimate it using our sample mean.

  1. For a sample mean (Xbar) = 20 and a sample size N = 25, compute a 95% confidence interval for . (Show the process you used to determine the CI bounds)

  1. Explain the meaning of the confidence interval you have found.

Please walk me through the process, I have already attempted these questions but I am struggling with confidence in my answers.
