For the problems 2 and 3 , test the hypotheses using the following steps. ( 24 points each) (1) State research hypothesis ( 2 points) (2) State assumptions ( 2 points) (3) State statistical hypotheses in symbols ( 2 points) (4) State the significance level and the critical value (4 points) (5) State the decision rules ( 2 points) (6) Compute the sum of squares, mean squares, and F (4 points) (7) Create the ANOVA table (4 points) (8) Draw the graph of group means ( 2 points) (9) State the conclusion ( 2 points) 2. An experiment was conducted to determine effects of a central nervous system stimulant on maze performance in rats. Twelve rats were randomly assigned to either a control (rats were injected with a placebo) or an experimental (rats were injected with 10mg of the stimulant) condition. The data below represent the number of errors made by each rat while running through the maze. Test the hypothesis that this stimulant affects the performance of rats at =.05
