Question
3: The average cost of tuition and room and board at a small private college in the south-central
region of the United States is reported to be S18,500 per term. A financial advisor believes that
the average cost in Arkansas is less than S18,500. What are the null and alternative hypotheses
for this study?
А.
Họ: u = S18,500; H: u S18,500
В.
Họ: u2S18,500; H: u <$18,500
С.
Họ: u<S18,500; H.: u > S18,500
D.
None of the above are correct.
4: If the chosen significance level is a - .05, then
А.
there is a 5% probability of accepting a true null hypothesis.
В.
there is a 5% probability of accepting a false null hypothesis.
С.
there is a 5% probability of rejecting a false null hypothesis.
D.
there is a 5% probability of rejecting a true null hypothesis.
