• A) the mean error is zero, error variance is nonconstant, and the errors are independent and normally distributed.
• B) the mean error is not zero, error variance is constant, and the errors are independent and normally distributed.
• C) the sample size is large (at least 30), and errors are independent and normally distributed.
• D) the mean error is zero, error variance is constant, and the errors are independent and normally distributed.
