Question

What is the critical value for a chi-square test with 13 degrees of freedom at the 1 percent level of significance

Answer 1

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
