MGMT1050 Practice Final Examination PART I - PROBLEM RECOGNITION (24 MARKS, 2 MARKS EACH) Instructions: For each of the scenarios below, write the null and alternative hypotheses and indicate the most appropriate statistical test. You are not required to conduct the test, just choose the most suitable test from the following options: z-test; t-test; χ 2 -test; F-test, ANOVA. Notes : (1) Be specific in your answers: for example, specify the type of ANOVA required (one-way, randomized block, or two-way), or whether you would use the t-test for equal variances or not. (2) When writing hypotheses for two population tests, use meaningful indexing. For example, if the question asks to compare Canada and the US, write μ c - μ u as opposed to μ 1 - μ 2 . (3) Write all relevant hypotheses for each of the questions. 1 . Do “captive stores” have better or worse pricing? In order to test this question, a researcher selected 20 Sony products and collected the prices for these items at three stores: the “Sony Style” store, “The Source” and a local independent electronics retailer.

    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.
