OBJECTIVES
SWBAT
 Describe the three necessary conditions necessary
for doing inference involving two population
means.
 Clarify the difference between the two-sample z
statistic and the two sample t statistic
 Identify the two practical options for using two
sample t-procedures and how they differ in terms
of computing the number of degrees of freedom.
 Conduct a two-sample significance tes for the
difference between two independent means using
the inference Toolbox
 Expain what is meant by “pooled two sample tprocedures”

Review

Identify the mean and standard deviation of the
sampling distribution of pˆ1  pˆ 2
List the conditions under which the sampling
distribution of pˆ1  pˆ 2 is appproximaely
Normal
Identify the standard error of pˆ1  pˆ 2 when
constructing a confidence interval for the
difference between two population proportions
Identify the three conditions under which it is
appropriate to construct a confidence interval
for the differences between two population
proportions
Construct a confidence interval for the
difference between two population portions
using the Toolbox for confidence intervals
Explain how the standard error of pˆ1  pˆ 2
differs between the constructing a confidence
interval for pˆ1  pˆ 2 and performing a
hypothesis test for Ho: pˆ1  pˆ 2 =0
List the three conditions that need to be
satisfied in order to do a significance test for the
difference between two proportions.
Conduct a significance test for the difference
between two portions using the inference tool
box.

UNIT #7 Inference for the Mean of a Population
Suggested Time Allotment: 9 Blocks
INSTRUCTIONAL OBJECTIVES
Students will be able to:
1. use one-sample t procedure create confidence interval for the
mean when variance is not known.
2. use one-sample t procedure perform hypothesis tests for the
mean when variance is not known.
3. determine if assumptions have been met for using t tests
4. perform hypothesis tests and create confidence intervals using
matched pairs t procedures.
5. compare means for two independent samples by using
hypothesis tests and confidence intervals.
6. apply confidence intervals and hypothesis testing of means to
real world situations
7. use appropriate software and/or graphing calculator to test a
mean or difference of two means
SUBJECT MATTER CONTENT
1. hypothesis testing and confidence intervals for small samples
or samples with unknown variances
2. hypothesis testing and confidence intervals for difference of
means paired or dependent samples
3. hypothesis testing and confidence intervals for difference of
two means independent samples, population variances equal
or not equal.
