Significance Tests and Decision Making

The p-value of a hypothesis test is .0281.  Is this result significant at the 5% significance level?

• Yes, because .0281 > .05.

• Yes, because .0281 < .05.

• No, because .0281 < .05.

• No, because .0281 > .05.

The p-value of a hypothesis test is .0281. Is this result significant at the 1% significance level?

• Yes, because .0281 > .01.

• No, because .0281 > .01.

• No, because .0281 < .01.

• Yes, because .0281 < .01.

Find the critical value(s) for a test using the following hypotheses and a 5% significance level.

• Z* = -1.960

• Z* = -1.645

• Z* = 1.645

• |Z*|= 1.645

Find the critical value(s) for a test using the following hypotheses and a 10% significance level.

• |Z*|= 1.282

• Z*= -1.645

• |Z*|= 1.645

• Z*= -1.282
