      What critical value t* should you use? In Table B, we consult the row corresponding to df = n − 1 = 11. We move across that row to the entry that is directly above 95% confidence level on the bottom of the chart. The desired critical value is t* = 2.201. Notice that the corresponding standard Normal critical value for 95% confidence is z* = 1.96.
