Estimation Discussion D

Question Description

Week 7 Post (300+ words):

Give an example of an interval estimate of an average or proportion you may use in your daily life. For instance, you may say that you are pretty sure your average commute time is between 25-30 minutes, or you are fairly confident that between 60-65% of the population love dogs. Collect some data to see how well your intuition is working. First, does your sample data meet all assumptions necessary to construct the confidence interval of the type you need? Even if it doesnt, construct and interpret the confidence interval.

Choose two of your classmates posts. Collect your own data and find your own confidence interval and compare. If, for example, your point estimate is less than your classmates point estimate, can you be sure or confident that the corresponding parameter is less? Why or why not, and what could you do to try to figure it out? What impact do the bounds of the intervals have?
