When we say we have a confidence level of 95 what do you, Ask an Expert

Statistics

1. When we say we have a confidence level of 95%, what do you think our "margin of error" is?

2. If we move the level of confidence from 95 to 99%, what will happen to our margin of error? What will happen to the width of our confidence interval?

3. Would we have gotten a better feel for the amount of flour needed if we'd used a larger sample? Why (mathematically) would this happen?
