1. In testing for the equality of means from two always
independent populations, if the hypothesis of
equal population means is rejected at α = .01, it
will ________ be rejected at α = .05.
2. A new company is in the process of evaluating its PInternet − Pstore d.10.

about the residuals in a regression model?
12. The ________ regression method is used when the logistic
response variable is a qualitative or a categorical
