CHAPTER 1 LEARNING OBJECTIVES

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



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


null hypothesis.
G G




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


evidence it provides against a null hypothesis.
G G G G G G G



CLO1-4: Describe how the distance of the observed statistic from the parameter value specifiedby the
G G G G G G G G G G G G G G G


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


against the null hypothesis.

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

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.
G G G G



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



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


chance model is a plausible explanation for the data.
G G G G G G G G G




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


comment on strength of evidence against observed study results happening by chance
G G G G G G G G G G G G


alone.

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


correct explanation for the observed data.

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


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


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?
G G G G G G G G



A. The long-run proportion of Taekwondo matches in which the red uniform wearer

statistically significant?
G G




A. Yes, since 45 is larger than 40.
