Homework #7 - Hypothesis Testing (part 2)
The fourth homework covers material in chapters 8 (specifically 8.7) and chapter 9 (9-1
through9-4 and 9-6) . The materials in those sections imply the following skills as
being important:
- Concepts / Vocabulary: This homework continues to require an
understanding of the concepts in the previous homework assignment - specifically, the
concepts of population, sample, estimator, parameter, point estimate, confidence interval,
and sampling distribution of an estimator, statistical hypothesis, type I error, type II
error, significance level, power, p value, and t distribution.
- Hypothesis Testing - Goodness of Fit: Define and
conduct hypothesis tests to test whether a proposed probability model is good fit
for the distribution of observed data (e.g., is a Poisson model a good model for this
data).
- Hypothesis Testing - Two Samples: Define and
conduct hypothesis tests concerning the true relationship between the population
parameters of two populations (i..e., the difference between means, the difference between
two proportions, etc)..
1. Goodness of Fit (section 8-7)
8-63
2. Hypothesis Testing - Difference between two Means, Variances known
(Section 9-2)
9-1: Hypothesis testing and confidence intervals
3. Hypothesis Testing - Difference between two Means, Variances unknown
(Section 9-3)
9-25: Hypothesis testing and confidence intervals
9-16: Hypothesis testing
4. Hypothesis Testing - Paired-t Test (Section 9-4)
9-37, 9-39, 9-40: Hypothesis testing and sample size. These are the same
problem context
** You might consider also how you would construct a confidence interval around the
observed "difference"
5. Hypothesis Testing - Difference between two Proportions (Section 9-6)
9-55, 9-57: The same problem context
none yet.
