(1 pt) Find the critical values lower = x1-a/2 and zipper = xârz that correspond to 99% degree of confidence and the sample size n = 7. Xlower = Xipper =

Find the critical values χ2lower=χ21−α/2 and χ2upper=χ2α/2 that correspond to 99% degree of confidence and the sample size n=7.
χ2lower=       χ2upper=

Answer 1

here degree of freedom =n-1=7-1 =6

for 6 degree of freedom and  99% degree of  confidence χ2lower=0.676 ( please try 18.548 if this comes wrong)

for 6 degree of freedom and  99% degree of  confidence χ2upper=18.548 ( please try 0.676 if this comes wrong)
