write my assignment 16553

My teacher posed the following: for clarification I am not asking you how to answer these questions, I am asking how i would provide my own personal answers in the form of a 90% confidence interval. Thank you :

As a fun exercise, take the following little quiz. For your answer to each one, give a 90% confidence level: For example, if the question were “How many teams are in the NHL,” a student with no idea might give an answer of 5-40, a student with a good idea might give an answer of 28-32, and so forth. This exercise is intended to get you to think about confidence intervals and understanding the basic idea of what they are all about. It also illuminates the duality of confidence intervals–if you are 90% sure that the correct number is between X and Y, then 90% of all such confidence levels should contain the true value.

Of course many of these questions can easily be googled, but try not to do it. The point here is not to learn about MLK or about the moon, but about confidence intervals.
