For this discussion you will create an original word problem for your peers to solve. Your problem should require your peers to either use a One sample T test, Repeated or Independent samples T test. Please pick one only. In your word problem, you must include all of the relevant information needed for someone else to solve the problem correctly. If you are unsure of what information is needed to solve these T test, please double check the slides or your notes. Once you create your problem you must solve it for yourself and at the bottom of your original post include your T obtained value. For your problem you can sither give a small data set (no more than 5 numbers should be used per group) or you can provide the needed data to solve the problem. Remember that the goal of this is for your peers to be able to figure out what test needs to be used and have all of the information needed for them to solve the problem.
