Question

In a word association test activity , an experimenter would like to test if there is a difference in the reaction time elicited between when 10 participants were subjected to say whatever comes to their mind (free association) and  say the opposite or similar word of the stimulus word presented (partially controlled stimulus).

 

  1. Let’s assume there is adequate basis for a two tailed test. What is the non-directional alternative hypothesis?
  2. What is the null hypothesis?
  3. What is the conclusion? Use alpha of 0.05 2 tail.
