The criterion determines
 
  a. the critical value of the sample mean.
  b. the probability of the sample mean.

Question 2

Which of the following is not true of the criterion?

  b. Samples that meet the criterion occur more than 5 of the time.
  c. Behavioral researchers usually use 0.05 as their criterion probability.
  d. Sample means that occur with a probability less than that of the criterion probability are likely to represent some other population.

Question 3

What is the critical value?
 
  a. The outer end of the region of rejection
  b. The inner edge of the region of rejection
  c. The absolute value of the entire region of rejection
  d. The value of z needed to conclude that the population mean occurred by chance
