IV. Statistical Inference: Confirming
models
A. Confidence intervals
- The meaning of a confidence
interval
- Large sample confidence interval
for a proportion
B.
Tests of significance
- Logic of significance testing, null
and alternative hypotheses; p-values;
one- and two-sided tests; concepts of Type I and Type
II errors; concept of power
- Large sample test for a proportion
- Large sample test for a mean
- Large sample test for a difference
between two proportions

| Essential Question:
How does a confidence interval for
proportions compare to one for means? |
Ch. 12.1 Inference for Proportions
-
State the meaning of p-hat.
-
Create a large sample confidence
level for a proportion (p.665).
-
Perform a hypothesis test
comparing a large sample proportion (p-hat) against a know
population proportion (p).

- Lesson 1
- Essential Question: How
can inferences be draw for single sample proportions?
Warm up (individuals):
-
What type of
distribution is most useful for evaluating surveys for voting or yes
or no questions?
-
Why does the binomial
distribution start to look like a normal distribution when the
sample size is large?

| Essential Question:
Assuming an SRS and given equal
sized margins of error, is the sample size required to survey the
entire United States substantially larger than the one for
conducting the same survey in Greenville SC? |
Ch. 12.1, 12.2
-
Calculate the desired
sample size for a given margin of error in a proportion (p. 670).
-
Create a confidence
interval for comparing two sample proportions (p.681).
-
State the Ho used for
comparing two sample proportions.
-
Calculate the pooled
portion of successes using both samples.
-
Perform a hypothesis test
for comparing two sample proportions (p. 684).

- Lesson 2
- Essential Question: How
can inferences be draw for two sample proportions?
Warm up questions (individuals):
- What's the difference between p
and p-hat?
- What are the two rules of thumb
for modeling the binomial distribution with a normal distribution?
