Hypothesis testing

Use the data set attached. You want to come up with a question that can be addressed, partially answered, answered, or have some light shed upon it using a test for mean or proportion done on a sample drawn from one of these data sets. (You should also do at least one equivalent confidence interval.) Be sure you explain your question, why it is interesting to you and who else can use it, your sampling method, any descriptive statistics you think will be relevant, and your hypothesis test. (You do not need to take a random sample this time you can assume all the data is a random sample if you want.) Be sure to include H0, Ha, which test you used and what conditions were necessary for you to use it, your p-value, and what that means to your Ha and your original question. In addition make sure that you explain why you do each thing you do except the stuff that is done on the calculator. As always, you will be graded on how well you address the four QR objectives listed below. You do not have to organize your paper strictly that way but you can if you want to. Do not assume the reader knows this page – explain what you are doing and why at each step. The paper should be typed in a standard 12-point font and in a standard format (both computer format and paper format). If it is more than two pages you have probably said too much. I. Formulate a question and explain the decision process behind the choices made. II. Use statistical methods to gather and analyze data. III. Determine the reasonableness of the answer and explain the limitations of your method. IV. Interpret your results in a context appropriate for a broader audience. Please use the data set informatibcqon attached in the file
