Answer: 27.688

Explanation:

The critical chi-square value
$\chi^2_((df,\alpha))$ depends on significance level (
$\alpha$ ) and degrees of freedom (df) .

Given significance level: (
$\alpha$ ) = 1% = 0.01

Degrees of freedom (df)= 13

From the chi-square table, the critical chi-square value for df = 13 and
$\alpha =0.01$

is
$\chi^2_((df,\alpha))=27.688$

Hence, the required critical value = 27.688
