Questions
21 In order to determine the p-value of a hypothesis test, which of the following is not needed?
A 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
24 In a one-tail test for the population mean, if the null hypothesis is rejected when the alternative hypothesis is not true, then:
A a Type I error is committed
B a Type II error is committed
C a correct decision is made
D a two-tail test should be used instead of a one-tail test

Answer: a Type I error is committed
25 In a two-tail test for the population mean, if the null hypothesis is rejected when the alternative is true, then:
A a Type I error is committed
B a Type II error is committed
C a correct decision is made
D a one-tail test should be used instead of a two-tail test

Answer: a correct decision is made
26 In a criminal trial, a Type II error is made when:
A a guilty defendant is acquitted (set free)
B an innocent person is convicted (sent to jail)
C a guilty defendant is convicted
D an innocent person is acquitted

Answer: a guilty defendant is acquitted (set free)
27 A Type II error occurs when we:
A reject a false null hypothesis
B reject a true null hypothesis
C do not reject a false null hypothesis
D do not reject a true null hypothesis

Answer: do not reject a false null hypothesis
28 In a criminal trial, a Type I error is made when:
A a guilty defendant is acquitted (set free)
B an innocent person is convicted (sent to jail)
C a guilty defendant is convicted
D an innocent person is acquitted

Answer: an innocent person is convicted (sent to jail)
29 The probability of Type 1 error is referred as?

Answer: Alternative Hypothesis
34 A hypothesis which defines the population distribution is called?
A Null Hypothesis
B Statistical Hypothesis
C Simple Hypothesis
D Composite Hypothesis

Answer: Simple Hypothesis
35 If the assumed hypothesis is tested for rejection considering it to be true is called?
