A researcher conducts an experiment involving the effects of three levels of a drug on memory. Twelve participants are randomly assigned to one of three conditions.A different drug level is administered in each condition.Memory is measured 10 minutes after each subject receives the drug. The following scores are recorded.The higher the score, the better the memory. They obtained the following information:

Drug Levels

Group 1 Group 2 Group 3

6 9 14

10 7 13

8 9 15

12 13 19

mean of X1=9

meanof X2=9.50

mean ofX3=15.25

X1=36

X2=38

X3=61

X12=344

X22=380

X32=951

With this information, I need an ANOVA.
