PROBABILITY AND STATISTICS Lab, Seminar, Lecture 4. Behavior of the sample average X-bar The topic of 4th seminar&lab is the average of the population that has a certain characteristic. This average is the population parameter of interest, denoted by the greek letter mu. We estimate...
“when”, “where”, “what”… It's a precise statement of what the research project will achieve. RQ4 Why is determining the decision problem a critical step in any research endeavor? It’s an important step because it allows the researcher to determine whether it is really necessary to employ the research...
4% The Central Limit Theorem The Central Limit Theorem (CLT) is what our parametric inferential statistics are based upon. The question is, if you draw samples from a population and calculate the means of those samples, how close can you expect them to be to the population mean? The CLT addresses...

Synthesis/Potential Test Questions (PTQs) • What is statistics? Making an inference about a population from a sample. • What is the logic that allows you to be 95% confident that the confidence interval contains the population parameter? We know from the CLT that sample means are normally distributed around...

must first understand two important concepts: 1) sampling distributions of statistics, and 2) the central limit theorem. Sampling Distributions Imagine drawing (with replacement) all possible samples of size n from a population, and for each sample, calculating a statistic--e.g., the sample mean. The...

014) Equation: (b) Why is the normality assumption not a problem, despite the very small value of p? (Data are from Flying 120, no. 11 [November 1993], p. 31.) Because the sample size is very large, p is normally distributed by the Central Limit Theorem (CLT). The larger the sample the...
