What is the variance of a population? A) It is the difference in creating process maps. B) It is equal to the sum of the squared deviations from the mean, divided by the population size. C) It is equal to the standard deviation. D) It is the sum of the mean, median, and mode. B The variance, σ^2, of a population is equal to the sum of the squared deviations from the mean, divided by the population size. For a sample, the variance is equal to the sum of the squared deviations from the ...

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. - 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 variance from the variation of a new measurement." ...
