Find the value of X2 for 15 degrees of freedom and an area of .050 in the right tail of the chi-square
distribution.
Your Answer:
For this problem I must calculate: (1-.050)=.95, therefore X2=7.261
Look across the top of the chi-square distribution table for .050, then look down the left column for
15. These two meet at X2 =24.996.

Find the value of X2 for 17 degrees of freedom and an area of .050 in the left tail of the chi-square
distribution.
Your Answer:
For this problem, I must calculate (1-.050)=.95, therefore X2 =8.672
Since the chi-square distribution table gives the area in the right tail, we must use 1 - .05 = .95. Look
across the top of the chi-square distribution table for .95, then look down the left column for 17.
These two meet at X2 =8.672.
