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 of
evidence 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 the
chance 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 the correct
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 80
Taekwondo matches
C. Whether the red uniform kwearer kwins ka kmatch
D. k 0.50
Ans: kA; kLO: k1.1-1; kDifficulty: kEasy; kType: kMC
2. What kis kthe kstatistic kfor kthis kstudy?
A. The klong-run kproportion kof kTaekwondo kmatches kin kwhich kthe kred kuniform
kwearerkwins
B. The kproportion kof kmatches kin kwhich kthe kred kuniform kwearer kwins kin ka ksample kof

C. Whether kthe kred kuniform kwearer kwins ka kmatch
D. k 0.50
Ans: kB; kLO: k1.1-1; kDifficulty: kEasy; kType: kMC
3. Given kbelow kis kthe ksimulated kdistribution kof kthe knumber kof k―red kwins‖ kthat kcould

kobserved kresult kstatistically ksignificant?
A. Yes, ksince k45 kis klarger kthan k40.
B. Yes, ksince kthe kheight kof kthe kdotplot kabove k45 kis ksmaller kthan kthe kheight kof
