Alternate hypothesis - correct answer -A statement that is
accepted if the sample data provide sufficient evidence that the
null hypothesis is false.
Type 1 error - correct answer -Rejecting null hypothesis when it
is true
Type 2 error - correct answer -Accepting null hypothesis when
you should have rejected it
Significance level - correct answer -The probability of a Type I
error. A benchmark against which the P-value compared to
determine if the null hypothesis will be rejected.
P value of a hypothesis - correct answer -probability of getting
sample data at least as inconsistent with the null hypothesis and
, Page | 2
thus supportive of the alternative hypothesis as the sample data
actually obtained
Drawing a conclusion - correct answer -to reach a conclusion
about the null hypothesis, directly compare P and . If P > , the
observed sample mean is not extreme enough to warrant
rejecting H0; more formally stated, there is insufficient evidence to
reject H0. If P there is sufficient evidence to reject H0 and accept
HA. In other words, the P-value is the smallest significance level
at which the null hypothesis can be rejected.
Hypothesis test and confidence intervals - correct answer -The
relationship between a hypothesis test and the corresponding
confidence interval is defined by the significance level ; the two
approaches are based on the same inferential logic, and differ
only in perspective. The hypothesis testing approach asks
whether is far enough away from to be considered extreme, while
the confidence interval approach asks whether is close enough to
to be plausible. In both cases, "far enough" and "close enough"
are defined by , which determines the used to calculate the
margin of error
Inferences for two population means - correct answer -
