Can you help me understand this Mathematics question?
One can calculate the 95% confidence interval for the mean with the population standard deviation known. This will give us an upper and a lower confidence limit. What happens if we decide to calculate the 99% confidence interval?
Your task for this discussion is as follows:
- Describe how the increase in the confidence level has changed the width of the confidence interval. Do the same for the confidence interval set at 80%.
- Include an example with actual numerical values for the intervals in your post to help with your explanations.
