   Question

   Researchers at the Open University Netherlands have written an article entitled “Relationship between ESL and the Psychological Characteristics Neuroticism, Self-efficacy and Coping.” To measure neuroticism, the N scale of the ABV (Amsterdam Biographical Questionnaire) is used. The scores range from 1 to 10.

   Suppose that ESL is measured by counting the number of months between the actual time of completion and the time of exit (e.g. -8 means that the student left school 8 months before studies were to be completed).

   Below are the collected data of 6 students from Eindhoven.

   

   We also know the following: SSX = 6.83, SSY = 116.83 and SP = -23.83.

   The following scatterplot belongs to the above data.

   

   Is there a significant correlation between the variables early abandonment and neuroticism in $\alpha = .05$?

   
   
   1. FALSE: No, because r = .84 and that is smaller than the critical value of .707
   2. FALSE: No, because r = .711 and that is smaller than the critical value of .811
   3. TRUE: Yes, because r = -.84 and that is greater in absolute value than the critical value of .811
   4. FALSE: Yes, because r = -.711 and that is greater in absolute value than the critical value of .707
