In preparation for the unit test, we reviewed Unit 5.4 on biased and unbiased point estimators, and Unit 5.5 on distributions of sample proportions.

Today, we reviewed material in Units 5.2 and 5.3 in preparation for the unit test.

Today, Joshua and I reviewed the material in Unit 5.1 in preparation for the unit test.

College Board Website, AP Statistics, Unit 5.8: The shape, center, and variability of the distribution of a difference in means; and how to interpret their parameters.

College Board Website, AP Statistics, Unit 5.7: the shape, center, and variability of the sampling distribution of a sample mean; and how to interpret parameters and probabilities for a sampling distribution of a sample mean. Unfortunately, Joshua did not do as well as we had hoped in the Unit 4 tests.

Joshua took the second half of the unit test.

Joshua took the first half of the unit test.

College Board Website. AP Statistics, Unit 5.6: Today, we worked through the exercises for this unit.

We reviewed unit 5.5 and then on the College Board Website, AP Statistics, we studied Unit 5.6, which covered the shape center, and variability of the sampling distribution of a difference in sampling proportions.

We finished our review of Unit 4 by completing units 4.9 through 4.12, which covered: combining random variables; finding the mean and standard deviation of a linear combination; calculating parameters of linear combinations; binomial random variables; the parameters of a binomial distribution; and calculating parameters for binomial and geometric distribution.
