1. What is a confidence-interval estimate of a parameter? Why is such an estimate superior to a point estimate? 2. Describe when you would use a t-score instead of a z-score when finding a confidence interval. 3. Suppose you want to increase the level of confidence without reducing the precision. What can you do? Thanks in advance!
