     For each of the following scenarios, determine the appropriate critical value(s) for comparison. On the cover sheet, you should include both the symbol and the value(s). (e. g. , Z_0. 025 = plusminus 1. 96)   
  
  Solution
a)
 Critical Value
 The Value of |t | with n-1 = 13 d.f is 2.16, (t =0.025) = 2.16
 c)
Critical Value
 The Value of |Z | at LOS 0.1% is 1.28, Z  = 1.28
