Montgomery, George C. Since 23 problems in chapter 8. This expansive textbook survival guide covers the following chapters and their solutions. Chapter 8. Key Statistics Terms and definitions covered in this textbook All possible subsets regressions A method of variable selection in regression that examines all possible subsets of the candidate regressor variables.

Eficient computer algorithms have been developed for implementing all possible regressions Analytic study A study in which a sample from a population is used to make inference to a future population. Stability needs to be assumed. The ARE of one test relative to another is the limiting ratio of the sample sizes necessary to obtain identical error probabilities for the two procedures.

Categorical data Data consisting of counts or observations that can be classiied into categories. The categories may be descriptive. Center line A horizontal line on a control chart at the value that estimates the mean of the statistic plotted on the chart. See Control chart. Central tendency The tendency of data to cluster around some value.

Central tendency is usually expressed by a measure of location such as the mean, median, or mode. Conditional variance. The variance of the conditional probability distribution of a random variable.

Control limits See Control chart. The correction factor can also be written as nx 2. Dependent variable The response variable in regression or a designed experiment. Distribution function Another name for a cumulative distribution function. Eficiency A concept in parameter estimation that uses the variances of different estimators; essentially, an estimator is more eficient than another estimator if it has smaller variance.

When estimators are biased, the concept requires modiication. Error mean square The error sum of squares divided by its number of degrees of freedom. Error propagation An analysis of how the variance of the random variable that represents that output of a system depends on the variances of the inputs.

A formula exists when the output is a linear function of the inputs and the formula is simpliied if the inputs are assumed to be independent. Estimate or point estimate The numerical value of a point estimator. Estimator or point estimator A procedure for producing an estimate of a parameter of interest.

An estimator is usually a function of only sample data values, and when these data values are available, it results in an estimate of the parameter of interest. First-order model A model that contains only irstorder terms.

Consider the hospital emergency department data given below. Let A denote the event that a visit is to hospital 1, and let B denote the event that a visit results in admittance to any hospital. Determine the number of persons in each of the following events.
