In Attribute Sampling,an Advance Estimate of the Expected Population Exception

question 43

Multiple Choice

In attribute sampling,an advance estimate of the expected population exception rate is necessary to plan the appropriate sample size.The relationship of expected population exception rate (EPER) to sample size is

• A)direct (small EPER = small sample).
• B)inverse (small EPER = large sample).
• C)a variable (sometimes small,sometimes large)dependent on other factors present.
• D)indeterminate.

Definitions:

Pooled Variance Estimator

An estimate of variance that combines the variances from two or more samples, assuming that they come from populations with the same variance.

MSE from ANOVA

Mean Square Error derived from Analysis of Variance, indicating the average of the squares of the deviations of observations from their group means.

Equal Variances T-Test

A statistical test used to determine if two populations have equal variances, assuming that the populations are normally distributed and independent.

Completely Randomized Design

A research design in which subjects are randomly assigned to experimental groups in an entirely unsystematic way, ensuring each subject has an equal chance of being assigned to any group.
