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 ofevid
ence 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 thecha
nce model is a plausible explanation for the data.
LO1.1-
5: Implement the 3S strategy: find a statistic, simulate results from a chance model, andcom
ment 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 thecorre
ct explanation for the observed data.

Questions 1 through 4:
Do red uniform wearers tend to win more often than those wearing blue uniforms in Taekwon
do 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 wo
n.
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 80Taek
wondo 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 80Taek
wondo 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 bycha
nce alone in a sample of 80 matches. Based on this simulation, is our observed result statisticall
y 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 thedotp
lot above 40.
C. No, since 45 is a fairly typical outcome if the color of the winner‘s uniform wasdet
ermined by chance alone.
