whether the test is one-tail or two-tail
[B]
the value of the test statistic
[C]
the form of the null and alternate hypotheses
[D]
the level of significance
Answer: the level of significance
(22)
The p-value of a test is the:
[A]
smallest significance level at which the null hypothesis cannot be rejected
[B]
largest significance level at which the null hypothesis cannot be rejected
[C]
smallest significance level at which the null hypothesis can be rejected
[D]
largest significance level at which the null hypothesis can be rejected
Answer: smallest significance level at which the null hypothesis can be rejected
(23)
If we reject the null hypothesis, we conclude that:
[A]
there is enough statistical evidence to infer that the alternative hypothesis is true
[B]
there is not enough statistical evidence to infer that the alternative hypothesis is true
[C]
there is enough statistical evidence to infer that the null hypothesis is true
[D]
the test is statistically insignificant at whatever level of significance the test was conducted at
Answer: there is enough statistical evidence to infer that the alternative hypothesis is true

[D]
a two-tail test should be used instead of a one-tail test
Answer: a Type I error is committed
(25)

a one-tail test should be used instead of a two-tail test
Answer: a correct decision is made
