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
U get a calculator and u put 4^2+7^4 n u put it in the calculator but the pic shows what a sqaure root looks like n u see the button with the x2 u can press that for when u put the 4 square root 2 then plus 7 n then u hit the button that has this symbol ^ n hit 4 then equal an itll give u the answer which is 2417.
