CHAPTER 1 LEARNING OBJECTIVES
CLO1-1: Use the čhanče model to determine whether an observed statistič is unlikely to oččur. CLO1-2:
Calčulate and interpret a p-value, and state the strength of evidenče it provides against the null
hypothesis.
CLO1-3: Calčulate a standardized statistič for a single proportion and evaluate the strength of
evidenče it provides against a null hypothesis.
CLO1-4: Desčribe how the distanče of the observed statistič from the parameter value spečified by the
null hypothesis, sample size, and one- vs. two-sided tests affečt the strength of evidenče against
the null hypothesis.
CLO1-5: Desčribe how to čarry out a theory-based, one-proportion z-test.
Sečtion 1.1: Introdučtion to Chanče Models
LO1.1-1: Rečognize the differenče between parameters and statističs.
LO1.1-2: Desčribe how to use čoin tossing to simulate outčomes from a čhanče model of the ran- dom
čhoiče between two events.
LO1.1-3: Use the One Proportion applet to čarry out the čoin tossing simulation.
LO1.1-4: Identify whether or not study results are statističally signifičant and whether or not the
čhanče model is a plausible explanation for the data.
LO1.1-5: Implement the 3S strategy: find a statistič, simulate results from a čhanče model, and
čomment on strength of evidenče against observed study results happening by čhanče alone.
LO1.1-6: Differentiate between saying the čhanče model is plausible and the čhanče model is the čorrečt
explanation for the observed data.

Questions 1 through 4:
Do red uniform wearers tend to win more often than those wearing blue uniforms in
Taekwondo matčhes where čompetitors are randomly assigned to wear either a red or blue
uniform? In a sample of 80 Taekwondo matčhes, there were 45 matčhes where the red uniform
wearer won.
1.What is the parameter of interest for this study?
A.The long-run proportion of Taekwondo matčhes in whičh the red uniform wearer wins
B.The proportion of matčhes in whičh the red uniform wearer wins in a sample of 80
Taekwondo matčhes
C.Whether the red uniform wearer wins a matčh
D. 0.50
Ans: A; LO: 1.1-1; Diffičulty: Easy; Type: MC
2.What is the statistič for this study?
A.The long-run proportion of Taekwondo matčhes in whičh the red uniform wearer wins
B.The proportion of matčhes in whičh the red uniform wearer wins in a sample of 80
Taekwondo matčhes
C.Whether the red uniform wearer wins a matčh
D. 0.50
Ans: B; LO: 1.1-1; Diffičulty: Easy; Type: MC
3.Given below is the simulated distribution of the number of ―red wins‖ that čould happen by
čhanče alone in a sample of 80 matčhes. Based on this simulation, is our observed result
statističally signifičant?
A.Yes, sinče 45 is larger than 40.
B.Yes, sinče the height of the dotplot above 45 is smaller than the height of the
dotplot above 40.
C.No, sinče 45 is a fairly typičal outčome if the čolor of the winner‘s uniform was
determined by čhanče alone.
