CHAPTER 1 LEARNING OBJECTIVES

CLO1-1: Use the chance model to determine whether an observed statistic is unlikely to occur.
m m m m m m m m m m m m m m
CLO1-2: Calculate and interpret a p-value, and state the strength of evidence it provides against the null
m m m m m m m m m m m m m m m m
hypothesis.
m
CLO1-3: Calculate a standardized statistic for a single proportion and evaluate the strength of evidence it
m m m m m m m m m m m m m m m
provides against a null hypothesis.
m m m m m
CLO1-4: Describe how the distance of the observed statistic from the parameter value specified by the null
m m m m m m m m m m m m m m m m
hypothesis, sample size, and one- vs. two-sided tests affect the strength of evidence against the
m m m m m m m m m m m m m m m
null hypothesis.

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

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

A. Yes, since 45 is larger than 40.
m m m m m m
B. Yes, since the height of the dotplot above 45 is smaller than the height of the dotplot
