Question

For each of the following sets of results, compute the appropriate test statistic, test the indicated alternative hypothesis, and compute the effects size(s) indicating their magnitude:

set	Hypothesis	1	2	D	n	α
a)	μ1 ≠ μ2	93.3	97.4	3.2	21	0.01
b)	μ1 > μ2	69.8	68	8.3	22	0.05
c)	μ1 < μ2	44.9	39.4	6.3	28	0.10

a)

Compute the corresponding effect size(s) and indicate magnitude(s).
d = ______; Magnitude: na trivial effect small effect medium effect large effect
r² = ______ ; Magnitude: na trivial effect small effect medium effect large effect

b)
