Answer: 27.688

Step-by-step 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
