Question 2

Rich performed a two-tailed test for an experiment in which n=15 . He could not find his t critical values table but he remembered the tcv at df = 20 . He decided to compare his tobt to this tcv. Is he more likely to make a Type I or a Type II error in this situation?
 
  What will be an ideal response?

Answer to Question 1

d

Answer to Question 2

Rich is more likely to make a Type I error in this case. He will use a tcv that is smaller than the one he should be using and thus he might call the result significant when it is not (a false alarm).
