Unit 5: Confidence Intervals Discussion
Please complete the following steps for your first discussion post and response.
Watch the video, Confidence Intervals (Confidence Intervals, 2013).
In the video, there is a discussion about how confidence intervals can be used to infer facts from your sample to the population.  Select a variable you are likely to work with in your career, then using the video and the text in this course, answer the following questions:

Describe the variable and how it might be used in your career (the example from the video is battery life).
Explain why you would need to use a sample to infer something about the population.
In your own words, explain why you believe that a confidence interval will accurately predict the mean of the population from which the sample was drawn?
What would happen if the confidence interval for your chosen variable did not include the value of the population mean?
What changes to sample would make you more certain that the confidence interval contained the value of the population mean?
