Kuya heard that oldest children tend to be more miserable about life than their youngest siblings (not taking into consideration the number of siblings in between). Kuya gathered data from 33 families and measured their scores on a misery scale. The lower the score, the more miserable the person tends to be.

 t test for dependent samples
 t test for independent samples

The obtained statistic is:

 t = - 2.48
 t = 2.48
 t = - 4.28

t = 4.28
