4. Hypothesis testing (Chapter 10 Section 3) You determine a reasonable value to use as your population mean based on your sample mean when stating the hypotheses. Remember that we are using our sample information to make a test a claim about the population. You will have to come up with a reasonable value for the parameter (population mean) to do this test. Recall, that with our examples during class, the value we used as the parameter was provided from a previous year's experiment or from comparable similar data. We don't have a previous year's experiment or comparable similar data; therefore, make a reasonable guess for a parameter to use. Also, continue the ow and make a statement like "From (previous year - input chosen year here), the population (state what is YOUR population) mean was (choose a value based of your sample). I want to know if the mean has (increased, decreased, changed - again YOU choose) from (chosen previous year). I will use the appropriate test to test this claim." Clearly state your null and alternative hypotheses. Your level of signicance (alpha) should be based on what you chose as your condence level from part 3. Make sure you use words to describe what you will be testing and write your conclusion appropriately. Clearly show the comparison between p-value and alpha. Reject/Do not Reject H 0 and what does this tell us about our alternative hypothesis statement
