AP Statistics Lesson Plans Chapter 13 Comparing two Population Parameter Judge the meaning, utility, and reasonableness of the results of symbol manipulations, including those carried out by technology. 4.3.12.D.3 Use surveys and sampling techniques to generate data and draw conclusions about large groups. 4.4.12.A.1 Advantages/disadvantages of sample selection methods (e.g., convenience sampling, responses to survey, random sampling) Evaluate the use of data in real-world contexts. 4.4.12.A.2 Accuracy and reasonableness of conclusions drawn Bias in conclusions drawn (e.g., influence of how data is displayed) Statistical claims based on sampling Design a statistical experiment, conduct the experiment, and interpret and communicate the outcome. 4.4.12.A.3 Analyze data using technology, and use statistical terminology to describe conclusions. 4.4.12.A.5 Measures of dispersion: variance, standard deviation, outliers Correlation coefficient Normal distribution (e.g., approximately 95% of the sample lies between two standard deviations on either side of the mean) DATE SECTION 1 to 2 block s 13-1 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” ASSIGNMENT Read pages 780-784 Page 785 #1, 3, 5 Read pages 788-790 Page 791 # 7, 9, 11 Read pages 792-800 page 801 # 13, 15 page 804 #17 – 23 odd METHOD OF INSTRUCTION Notebook presentation Worksheets….paired work. 1 to 2 block 13-2 1 block 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.
