Answer: 27.688
Step-by-step explanation:
The critical chi-square value
depends on significance level (
) and degrees of freedom (df) .
Given significance level: (
) = 1% = 0.01
Degrees of freedom (df)= 13
From the chi-square table, the critical chi-square value for df = 13 and 
is 
Hence, the required critical value = 27.688
The answer is -402
hope this helps !
