CHAPTER 1 LEARNING OBJECTIVES b6 b6 b6




CLO1-1: Use the chance model to determine whether an observed statistic is unlikely to occur.
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6



CLO1-2: Calculate and interpret a p-value, and state the strength of evidence it provides
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


againstthe null hypothesis.
b6 6
b b6 b6




CLO1-3: Calculate a standardized statistic for a single proportion and evaluate the strength
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


ofevidence it provides against a null hypothesis.
b6 6
b b6 b6 b6 b6 b6 b6



CLO1-4: Describe how the distance of the observed statistic from the parameter value specifiedby
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 6
b


the null hypothesis, sample size, and one- vs. two-sided tests affect the strength of
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


evidence against the null hypothesis.
b6 b6 b6 b6 b6




CLO1-5: Describe how to carry out a theory-based, one-proportion z-test.
b6 b6 b6 b6 b6 b6 b6 b6 b6




Section 1.1: Introduction to Chance Models b6 b6 b6 b6 b6




LO1.1-1: Recognize the difference between parameters and statistics.
b6 b6 b6 b6 b6 b6 b6



LO1.1-2: Describe how to use coin tossing to simulate outcomes from a chance model of the
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


ran-dom choice between two events.
b6 6
b b6 b6 b6 b6



LO1.1-3: Use the One Proportion applet to carry out the coin tossing simulation.
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6



LO1.1-4: Identify whether or not study results are statistically significant and whether or not
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


thechance model is a plausible explanation for the data.
b6 6
b b6 b6 b6 b6 b6 b6 b6 b6



LO1.1-5: Implement the 3S strategy: find a statistic, simulate results from a chance model,
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


and comment on strength of evidence against observed study results happening by
b6 6
b b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


chance alone.
b6 b6



LO1.1-6: Differentiate between saying the chance model is plausible and the chance model is
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


thecorrect explanation for the observed data.

Do red uniform wearers tend to win more often than those wearing blue uniforms in
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


Taekwondo matches where competitors are randomly assigned to wear either a red or
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


blue uniform? In a sample of 80 Taekwondo matches, there were 45 matches where
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


thered uniform wearer won.

3. Given below is the simulated distribution of the number of ―red wins‖ that could happen
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


by chance alone in a sample of 80 matches. Based on this simulation, is our observed

b b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


result statistically significant?
b6 b6 b6




A. Yes, since 45 is larger than 40.
b6 b6 b6 b6 b6 b6



B. Yes, since the height of the dotplot above 45 is smaller than the height of
b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6 b6


thedotplot above 40.
