Two Samples True/False 1. An independent sample experiment is an experiment in which there is no relationship between the measurements in the different samples. Answer: True Difficulty: Medium 2. When testing the difference between two proportions selected from populations with large independent samples‚ the Z test statistic is used. Answer: True Difficulty: Medium 3. In forming a large sample confidence interval for [pic]‚ two assumptions are required: independent samples and

Simple Random Sampling is done when every individual subject in the population has an equal chance of being selected for the sample‚ without any bias (Explorable). For example‚ if a researcher wants to represent the population as a whole‚ they can pick random numbers or names out a hat or use a program to randomly choose names so the information is not biased. Stratified Sampling is performed by‚ dividing the population into at least two (or more) groups or sections‚ which share certain characteristics

Hypothesis Testing: Two-Sample Case for the Mean Many cases in the social sciences involve a hypothesis about the difference between two groups (i.e. men and women‚ control and experiment). We analyze statistics from two samples‚ and the hypothesis and confidence interval would deal with the difference between two population means. The following factors are important in hypothesis testing: 1. probability theory 2. the sampling distribution of the statistic 3. the errors inherent
