Could someone check to see if I answered this correctly:
10.2: For each of the following pairs of null and alternative hypothesis, determine whether the pair would be appropriate for a hypothesis test. If a pair is deemed inappropriate, explain why.

a) Ho: µ ≥ 10, H : µ < 10 Answer: Appropriate
b) Ho: µ = 30, H : µ ≠ 30 Answer: Appropriate
c) Ho: µ > 90, H : µ ≤ 90 Answer: Appropriate
d) Ho: µ ≤ 75, H : µ ≤ 85 Answer: Inappropriate the alternative to the null hypothesis therefore in this case the alternative hypothesis must be: H : µ > 85
e) Ho: x (with a line above it) ≥ 15, H : x (with a line above it) < 15 Answer: Appropriate
f) ) Ho: x (with a line above it)= 58, H : x (with a line above it) ≠ 58 Answer: Appropriate

Inappropriate: The alternative to the null hypothesis would be: H : µ > 75
e) Ho: x (with a line above it) ≥ 15, H : x (with a line above it) < 15 Answer: Appropriate
f) ) Ho: x (with a line above it)= 58, H : x (with a line above it) ≠ 58 Answer: Appropriate
I would think that e & f would be inappropriate. $\bar{X}$ is not a population parameter (statistic).
