State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain.

(a) t=1.692

(b) t=0

(c) t=negative- 1.628

(d) t=negative -1.649

(a) For tequals

=1.692

1.692, should you reject or fail to reject the null hypothesis?

A.

Reject Upper H0, because tless than

B.

Failtoreject Upper H0, because tless than<1.637.

C.

Failtoreject Upper H0, because t greater than >negative1.637.

D.

Reject Upper H0, because tgreater than >negative 1.637.

(b) For =0, should you reject or fail to reject the null hypothesis?

A.

Reject Upper H0, because tless than

B.

Reject Upper H0, because t greater than >negative 1.637.

C.

Failtoreject Upper H0, because t greater than >negative 1.637.

D.

Failtoreject Upper H0, because t less than

(c) For t=negative 1.628, should you reject or fail to reject the null hypothesis?

A.

Failtoreject Upper H0, because tless than

B.

Reject Upper H0, because tless than

C.

Reject Upper H0, because tgreater than >negative 1.637.

D.

Failtoreject Upper HO, because tgreater than >negative 1.637.

(d) For t=negative 1.649, should you reject or fail to reject the null hypothesis?

A.

Reject Upper H0, because tgreater than >negative 1.637.

B.

Reject Upper H0, because tless than

C.

Failtoreject Upper H0, because tless than

D.

Failtoreject Upper H0, because tgreater than >negative 1.637.
