Luzerne County College Real World Inferential Statistics KFC Discussion

Your task is to perform some real-world inferential statistics.You will take a claim that someone has made, form a hypothesis from that, collect the data necessary to test the hypothesis, perform a hypothesis test, and interpret the results.If you use pre-existing data, rather than collecting it yourself, then you will need to do more analysis to get the full points.

You should try to come up with something of interest to you instead of some contrived situation.Several groups have tested to see if their company met their sales goals.One person tested to see if 60% of patients show up for their doctor’s appointment in the clinic where she worked.One waitress tested to see if the average tip was 15% another tested to see if gender plays a role in the amount of tip.

You need to submit a proposal defining what it is that you wish to test and how you wish to go about testing it (sampling techniques).The facilitator will peruse these proposals, make suggestions and give it back to you.If you can’t decide on a project or need help defining it, see the facilitator.

Be sure to define clearly what the population being studied is (Misericordia U students, people listed in the Wilkes-Barre phone book, people driving a car, etc.)

Make sure you get the project cleared with the facilitator before you go collect the data.The project should not cost you money to implement.It will take some time, however, and you should not wait until it’s due to get started on it.

While you are not precluded from doing any of the given examples, it is certainly better if you can come up with something original which has an interest to you.The facilitator will keep a copy of your final project.

Data sets can be found online or you will also can find data available in StatCrunch or on Stat Disk.
