Question:

For the following pairs of assertions, indicate which do not comply with our rules for setting up hypotheses and why (the subscripts 1 and 2 differentiate between quantities for two different populations or samples):
a. H0: μ = 100, Ha: μ > 100
b. H0: σ = 20, Ha: σ ≤ 20
c. H0: p ≠ .25, Ha: p = .25
d. H0: μ1 - μ2 = 25, Ha: μ1 - μ2 > 100
e. H0: S12 = S22, Ha: S12 ≠ S22
f. H0: μ = 120, Ha: μ = 150
g. H0: σ1/σ2 = 1, Ha: σ1/σ2 ≠ 1
h. H0: p1 - p2 = -.1, Ha: p1 - p2 < -.1
