4) Briefly state how you tested your hypothesis. 

5) Enter your two groups of data in the table below. Tell what each group is in the first row. For example, Group 1 might be the reaction time of your experimental group and Group 2 might be the reaction time of your control group.

6) What is the probability that the means of the two groups do not differ (that the difference is due to chance)?  p =

7) Do you accept your hypothesis or do you reject your hypothesis?

8) Explain why you accept or reject your hypothesis. Your answer must mention how the value of p is used to determine if the hypothesis is accepted or rejected.

9) Attach a printout of your statistical analysis (t-test). IMPORTANT- Please do not submit this assignment without a statistical analysis attached. It will not be graded without the analysis. Click here to perform this analysis now.

You may decide to use different sources when you write the formal report. It is OK to change your mind; the sources listed below do not need to be the same ones that you use in your report. All members of your group must have different sources. Click here for more information on finding literature sources, citing literature, and appropriate literature sources. This assignment will not be graded unless two appropriate sources of literature are listed below.

12) Attach the two literature sources listed above to this page. IMPORTANT- Please do not submit this assignment without at least two appropriate literature sources attached. It will not be graded unless copies of the literature are attached.
