Dr.Hinson wants to investigate if rats fed a diet enriched with omega will do better at a maze learning task then when these same rats are given a normal diet.He has a total of 30 rats for his experiment.In Dr.Hinson's study if he is using a total of 30 rats what is his degrees of freedom?
A)28
B)30
C)29
D)27

The degrees of freedom for this experiment would be 29, as it is calculated by subtracting the number of groups being compared from the total sample size (df = n - 1). In this case, Dr. Hinson is comparing two groups (rats on enriched diet vs. rats on normal diet), so the degrees of freedom would be 29 (30-1-1 = 29). Therefore, the correct choice is C.
