Question
If you use a .05 level of significance in a? two-tail hypothesis? test, what decision will you make if ZSTAT = ?1.671.67??
1.Determine the decision rule. Select the correct choice below and fill in the answer? box(es) within your choice.
?(Round to two decimal places as? needed.)
A.) Reject H0 if ZSTAT <? _____ or ZSTAT>+_______
B.) Reject H0 ____<ZSTAT<______
C.) Reject H0 if ZSTAT>_____
D.) Reject H0 if ZSTAT<?______
2. State your conclusion. Choose the correct answer below.
A.) Since ZSTAT does not fall into the rejection? region,reject H0.
B.) Since ZSTAT falls into the rejection? region, reject Upper H0.
C.) Since ZSTAT falls into the rejection? region, do not reject Upper H0.
D.) Since ZSTAT does not fall into the rejection region do not reject Upper H0.
Explanation / Answer
Level of significance = 0.05
Our test is a two-tail test.
Critical value = 1.96
1) Decision rule
| z | > 1.96 we reject H0
So correct option is
A) Reject H0 if ZSTAT < ? 1.96 or ZSTAT > + 1.96
2) ZSTAT is does not fall into the rejection region.
So correct option is
D) Since ZSTAT does not fall into the rejection region do not reject Upper H0.
