Question

Researchers compared the effectiveness of a mood induction technique (exposure to depressing film footage) across 3 different groups of 11 participants each: 1) 0 minutes exposure (Control Group), 2) 10 minutes exposure, & 3) 20 minutes exposure.  The response variable is the score on the Beck Depression Inventory (higher score = more depressed mood). 

M1 = 7 M2 = 11 M3 = 12
SS= 56 SS= 96 SS= 62
n1 =   11  n2 =   11 n3 =   11

SSTOTAL = 368

Which of the hypotheses is listed incorrectly? Select all that apply

a)H0: μ1 > μ2 > μ3

B)H0: μ1 = μ2 = μ3

c)H1: μ1 ≠ μ2 ≠ μ3
 
d)H1: μ1 < μ2 < μ3
