Determine the X2 percentile that is required to construct each of the following CI\'s: a) Confidence level= 95%, degrees of freedom= 24, one-sided (upper) b) Confidence level= 99%, degrees of freedom= 9, one-sided (lower) c) Confidence level= 90%, degrees of freedom= 19, two-sided Solution looking at the chi distribution table a) 36.415 b) 2.088 c) 11.651 and 27.204.

1. Determine the X2 percentile that is required to construct each of the following CI's:
a) Confidence level= 95%, degrees of freedom= 24, one-sided (upper)
b) Confidence level= 99%, degrees of freedom= 9, one-sided (lower)
c) Confidence level= 90%, degrees of freedom= 19, two-sided
Solution
looking at the chi distribution table a) 36.415 b) 2.088 c) 11.651 and 27.204
