Rejection/Acceptance of Hypothesis
qEvidences
from the sample that is inconsistent with the stated hypothesis
leads to the rejection of the hypothesis, whereas evidence supporting
the hypothesis leads to its acceptance.
qThe
rejection of a hypothesis is to conclude it is false.
qThe acceptance of a
statistical hypothesis is a result of insufficient evidence to reject it and
does not necessary imply that it is true.
qTherefore,
it is better to state a hypothesis that we wish to reject.
Hypotheses that we
formulate with the hope of rejecting are called null hypothesis and are
denoted by Ho.
