OB. Hypothesis tests that produce similar P-values always have the same conclusion.
OC. Hypothesis tests that result in the same conclusion do not necessarily have the same P-value.
D. A difference in conclusions between two hypothesis tests does not necessarily mean that the test with the result that is deemed "statistically significant" is actually much more significant than
the test with the result that is deemed "not statistically significant."
d. From part a, part b, and part c, explain why important information is lost by reporting the result of a test as "P-value ≤0.05" versus "P-value > 0.05," or as "reject Ho" versus "Do not reject Ho,"
instead of reporting the actual P-value.
A. The actual P-value is more informative because the strength of the evidence varies based on the value.
