Given$\mathrm{巍}\left(\mathrm{t}鈮�{\mathrm{t}}_0\right)=0.025$where$\text{df}=11$

By using t- distribution table, we will see the row with 11 degrees of freedom and column corresponds to$伪=0.025$ in the one-tail.

Hence from the critical values we get $t_{0.025,11}=2.201$

Given$巍(\mathrm{t}鈮�{\mathrm{t}}_0)=0.01$where$\text{df}=9$

By using t- distribution table, we will see the row with 9 degrees of freedom and column corresponds to$伪=0.01$ in the one-tail.

Hence from the critical values we get$t_{0.01,9}=2.821$

Given$\mathrm{巍}\left(\mathrm{t}鈮�{\mathrm{t}}_0\right)=0.005$where$\text{df}=6$

By using t- distribution table, we will see the row with 6 degrees of freedom and column corresponds to$伪=0.005$ in the one-tail.

Hence from the critical values we get$t_{0.005,6}=3.707$

Given$\mathrm{巍}\left(\mathrm{t}鈮�{\mathrm{t}}_0\right)=0.05$ where$\text{df}=18$

By using t- distribution table, we will see the row with 18 degrees of freedom and column corresponds to$伪=0.05$ in the one-tail.

Hence from the critical values we get $t_{0.05,18}=1.734$.
