Week 4 Exercise 1 1. Define the following terms in your own words: a) A statistical procedure for deciding whether the outcome of your study supports a particular theory. b) The .05 significance level is when the null hypothesis is rejected because there is less than a 5% chance of getting your results if the null hypothesis is true. c) A two-tailed test is used in hypothesis testing for a non-directional hypothesis. In a two-tailed test the probability of the null hypothesis being rejected is split between the two sides of the distribution. 2. You shouldn’t conclude that your research supports the null hypothesis because it is still possible that your research hypothesis is still correct, but that the results were not extreme enough to reject the null hypothesis. 6. Steps of hypothesis testing: 1) Restate the question as a research hypothesis and null hypothesis using the two populations. POP 1: Students that are not allowed to use their sense of smell.

    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.
