Directions:
You will use a significance level of 0.05
For each part:
Include any equations that would be used to solve in their original (symbolic) format, even if you solve with a calculator (so if you find the test statistic with the calculator you will tell the equation for the test statistic and then show the work for using the calculator).
Show all of your work!
If you use technology for any parts, you must include what you put into the technology along with the technology outputs.
If you solve by hand, show/explain how you found the solution
***When you post your final project, make sure that you include part 1 in the post.
Each student in the class will have a unique project.
You will need to collect at least 30 (numerical) data values that will allow you to test the sample population or sample mean against the population proportion or population mean. So pick a topic where you can easily find the population value and where you can easily get at least 30 data values for your sample (my examples below would cost me money to complete, which if I were I student I would probably not want to do.. but there are many ideas that you can come up with that will not cost you anything. These examples are just so you have an idea of what you are expected to do for the proposal).
DO NOT CONTINUE WITH THE PROJECT UNTIL THE PROPOSAL HAS BEEN APPROVED!
The types of studies you can do are (because these are the types of hypothesis tests we learn in this class):
One Population Proportion (Chapter 8) – You will choose a topic with a “population proportion” because you think the proportion is actually not equal to p, you think it is actually less than p, or you think it is actually greater than p (you will only pick one, you will NOT need to test all three). So you will collect a sample of at least 30 data values that will allow you to test this theory.
One Population Mean (Chapter 9) – You will choose a topic with a “population mean” because you think the mean is actually not equal to , you think the mean is actually less than , or you think the mean is actually greater than (you will only pick one, you will NOT need to test all three). So you will collect a sample of at least 30 data values to test this theory.
