   Question

   A clinical psychologist compares stress symptoms between three groups (control, cognitive therapy, psychoanalytic therapy) in 60 subjects using a one-factor ANOVA (“One-way ANOVA”).

   The researcher calculates the following three confidence intervals (‘confidence intervals’). Which conclusion about differences between the three groups is correct?

   BI $\mu_{controle-cognitief} = (1.48, 6.48)$

   BI $\mu_{controle-psychoanalytisch} = (-0.38, 4.73)$

   BI $\mu_{cognitief-psychoanalytisch} = (-5.09, -0.09)$

   
   
   1. FALSE: The control group differs from both the cognitive and psychoanalytic groups.
   2. TRUE: The cognitive group differs from both the control and psychoanalytic groups.
   3. FALSE: The psychoanalytic group differs from both the control and cognitive groups.
   4. FALSE: Only the control group and the cognitive group differ from each other.
