Resolved: difference between one sided and two sided hypothesis tests

one side testing :   (1-α) 
two sided tests :    (1-α/2) 
and 
critical value for one sided is :    (Z)
Critical value for two sided is :    (Z α/2)
      
            is that ?

Hi Gautam!

Thanks for reaching out!

Essentially, yes.

One-sided hypothesis tests determine if a parameter is greater than or less than a specified value, using a significance level α and a critical value Z1−α. Two-sided hypothesis tests determine if a parameter is different from a specified value, splitting the significance level α between two tails, using a critical value Z1−α/2​.

Keep up the good work!

Best,

Ivan
