    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: ≥ 10, H : < 10 Answer: Appropriate
    b) Ho: = 30, H : ≠ 30 Answer: Appropriate
    c) Ho: > 90, H : ≤ 90 Answer: Appropriate
    d) Ho: ≤ 75, H : ≤ 85 Answer: Inappropriate the alternative to the null hypothesis therefore in this case the alternative hypothesis must be: H : > 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 : > 75

    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).
