Answer:
Options B, C, D & E do not comply with the rules for setting up hypotheses
Step-by-step explanation:
(A). H0: m = 100, Ha: m > 100.
These hypotheses fully complies with our rules.
B). H0: s = 20, Ha: s 20.
H0 is not an equality claim such as σ = 20. Hence, these hypotheses are not in compliance with our rules.
(C). H0: p -:: .25, Ha: p = .25
H0 should definitely contain the equality claim, although Ha contains it here. Thus, these are not legitimate and don't comply with our rules
(D)H0: m1 - m2 = 25, Ha: m1 - m2 > 100
The given value of 25 for m1 - m2 in H0 should also appear in Ha,but it does not do so here, so it doesn't comply with our rules.
E)H0: S2 = S2, H : S2 -:: S2
Each S2 is a statistic and so it does not belong in a hypothesis.
- its the answer
