Week 06: Hypothesis Testing (Sols) 1. Review Fill in the following blanks with the appropriate letter found in the options below. Options may be re-used for more than one blank, or may not be used at all. The basic structure of testing a hypothesis is the following: 1. Setting up your question a. A : Fully specified chance model under which you can simulate the data. It normally says the data was generated at random under specified assumptions about the randomness b. E : States that there is some other reason (other than chance) as to why the data differ from the expected predictions of the model specified by the other hypothesis 2. Pick a F a. We should be able to compute this quantity on the observed data, as well as any samples we might simulate in the future b. Values of the F should help you differentiate between the null hypothesis and the alternative hypothesis c. D : Value you get when computing this quantity on the actual observed data 3. Simulate the F under the A a. Create a(n) J of the test statistic in order to approximate the B assuming the A was true 4. Concluding your test: a. P-value: The chance, under the model specified by the A , that the test statistic is equal to the D or even further in the direction of the E b. G : If the P-value is below that point, you reject the null hypothesis in favor of the alternative. A typical one is H Word Bank A. Null Hypothesis B. Probability distribution C. P-Value D. Observed Value of the Test Statistic E.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
