stratified random sampling A form of probability sampling; a random sampling technique in which the researcher identifies particular demographic categories of interest and then randomly selects individuals within each category. Parameter A numerical characteristic of a population, such as a population mean μ, a population standard deviation σ, a population proportion p, and so on. Target Population The population for which statistical inferences such as point estimates are mad...

Doubling the size of the sample will reduce the standard error of the mean The sample mean is the point estimator of U A simple random sample of size n from an infinite population of size N is to be selected. Each possible sample should have the same probability of being selected Which of the following statements regarding the sampling distribution of sample means is incorrect? The standard deviation of the sampling distribution is the standard deviation of the populatio...

(T/F) When we drop a variable from a model, the total sum of squares (TSS) increases. - FALSE. The TSS is the variation of Y around its sample average ~Y . It is unrelated to the number of X's used to explain Y . (T/F) If X and Y are independent, the conditional probability density function f(XjY )(XjY ) is equal to the marginal probability density function fX(X) - TRUE (T/F) The Adjusted R-squared (~R^2) is always greater than or equal to the R-squared (R^2) - FALSE. Because [(n-1)/(...

The prediction interval of one member of the population will always be larger than the confidence interval of the mean response for all members of the population when using the same predicting values. (T/F) - correct answer True. See 1.7 Regression Line: Estimation & Prediction Examples "Just to wrap up the comparison, the confidence intervals under estimation are narrower than the prediction intervals because the prediction intervals have additional va...
