If the population standard deviation is known, the 95% confidence interval for the mean can be computed. As a result, onewill have a higher and lower confidence limit. What would happen if we chose to compute the confidence interval of 99%? How does the breadth of the confidence interval alter as the confidence level rises? Apply the same logic to the 80% confidence interval. To aid in my understanding of your explanations, kindly provide an example where the intervals have actual numerical values.
