O Reject H1 O Reject Ho O Reject HA Retain (Fail to reject) Ho Question 22 1 pts The estimated standard error of the mean is used in the numerator of the t test formula O denominator of the t test formula numerator of the z test formula O denominator of the z test formula Question 23 1 pts A one sample t test has n= 12. If using a two-tail test (proportion in two tails combined) with an alpha - 05, the critical t score boundaries- O +- 1.729 O +: 1725
