18. Regarding the standard error of the estimate (SEE or Sy/x)-more than one answer may be correct a. The SEE describes the dispersion of x, y points around the regression line b. If the random errors for both methods are identical, the SEE will be approximately 1.4 times a typical SD c. The SEE is used to evaluate the accuracy of a method based on hemolysis and lipemia interference experiments The SEE is sensitive to random error d.

If alpha is set to .05, what will the level of Type II error be? 0.05 0.95 0 Cannot say Heteroscedasticity occurs when: there are larger values on X than Y. there is a linear relationship between X and Y. more error is accounted for than remains. variability in Y depends on the exact value of X. The variables that are measured throughout the experiment are called: Control Dependent variable Independent variable Responding variable

:2. A study was conducted in which participants looked at photographs of various people and guessed how old each photographed person was. Then the amount of error in each guess was calculated, and this was used as a response variable in regression analyses. Here are the names of the variables used; these will be referenced in the questions below: Error: Difference between guessed age and true age.
