Three Multiple Choice Questions:

In 2018, Portland took a census where they asked residents which coffee shop was their favorite: 32% preferred Collegetown Bagels (CTB), 25% preferred Gimme! Coffee, and 43% preferred Starbucks. In 2019, Portland University asked a simple random sample of 300 graduate students to answer the same question. Of the students surveyed, 93 preferred CTB, 94 preferred Gimme! Coffee, and 113 preferred Starbucks. We want to answer the research question: Are the coffee shop preferences of Portland University Graduate Students different from the population of Portlanian? Which null hypothesis is appropriate for the above research question. Here pi, P2, and p3 refer to the probability that a Portland University Graduate Student prefers CTB, Gimme! Coffee, or Startbucks, respectively. (a) p1 = 0.32, p2 = 0.25, p3 = 0.43 (b) p1 = 0.31, p2 = 0.31, p3 = 0.38 (c) PI = P2 = P3 (d) None of the above Continuing with the setup of the previous question suppose we ran the following code to answer the research question and got the corresponding output. students_coffee
