Question
State whether the standardized test statistic z indicates that you should reject the null hypothesis.
(a) z= 1.225
(b) z = - 1.329
(c) z = - 1.517
(d) z = - 1.158
2 =-1285
(a) For z= 1.225, should you reject or fail to reject the null hypothesis?
O A. Fail to reject H, because z< - 1.285.
O B. Reject H, because z> - 1.285.
O C. Fail to reject H, because z> - 1.285.
O D. Reject H, because z<- 1.285.
