If we are constructing a 90% confidence interval for the variance of a population using a sample of size 16, the two critical values for chi-square from the table that we need to use are and (use the three decimal place accuracy that the table gives you)
wondering if I have to take 16-1 for this question.
Homework Answers
Solution :
Given that,
n = 16
df = 16 - 1 = 15
Two critical values are
2L
=
2
/2,df
= 24.996
2R
=
21 -
/2,df = 7.261
