CHAPTER 1 LEARNING OBJECTIVES
CLO1-1: Use the chance model to determine whether an observed statistic is unlikely to occur.
CLO1-2: Calculate and interpret a p-value, and state the strength of evidence it provides
againstthe null hypothesis.
CLO1-3: Calculate a standardized statistic for a single proportion and evaluate the
strength ofevidence it provides against a null hypothesis.
CLO1-4: Describe how the distance of the observed statistic from the parameter value
specifiedby the null hypothesis, sample size, and one- vs. two-sided tests affect the
strength of evidence against the null hypothesis.
CLO1-5: Describe how to carry out a theory-based, one-proportion z-test.
Section 1.1: Introduction to Chance Models
LO1.1-1: Recognize the difference between parameters and statistics.
LO1.1-2: Describe how to use coin tossing to simulate outcomes from a chance model of the
ran-dom choice between two events.
LO1.1-3: Use the One Proportion applet to carry out the coin tossing simulation.
LO1.1-4: Identify whether or not study results are statistically significant and whether or
not thechance model is a plausible explanation for the data.
LO1.1-5: Implement the 3S strategy: find a statistic, simulate results from a chance
model, and comment on strength of evidence against observed study results
happening by chance alone.
LO1.1-6: Differentiate between saying the chance model is plausible and the chance model
is thecorrect 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 matches where competitors are randomly assigned to wear either a
red or blue uniform? In a sample of 80 Taekwondo matches, there were 45
matches where thered uniform wearer won.
1. What is the parameter of interest for this study?
A. The long-run proportion of Taekwondo matches in which the red uniform
wearerwins
B. The proportion of matches in which the red uniform wearer wins in a
sample of 80Taekwondo matches
C. Whether the red uniform wearer wins a match
D. 0.50
Ans: A; LO: 1.1-1; Difficulty: Easy; Type: MC
2. What is the statistic for this study?
A. The long-run proportion of Taekwondo matches in which the red uniform
wearerwins
B. The proportion of matches in which the red uniform wearer wins in a
sample of 80Taekwondo matches
C. Whether the red uniform wearer wins a match
D. 0.50
Ans: B; LO: 1.1-1; Difficulty: Easy; Type: MC
3. Given below is the simulated distribution of the number of ―red wins‖ that could
happen bychance alone in a sample of 80 matches. Based on this simulation, is our
observed result statistically significant?
A. Yes, since 45 is larger than 40.
B. Yes, since the height of the dotplot above 45 is smaller than the height
of thedotplot above 40.
