QUESTION:
Find \(\chi_{\alpha / 2}^{2} \text { and } \chi_{(1-\alpha / 2)}^{2}\) from table IV, Appendix D, for each of the following:
a. n = 10, \(\alpha=.05\)
b. n = 20, \(\alpha=.05\)
c. n = 50, \(\alpha=.01\)
ANSWER:Solution:
Step 1 of 3:
-
The claim is to find
and
We have, n = 10, and = 0.05
= 0.05,
= 0.025
Then, n = 10, df = n - 1
= 9
Then, = 19.023 ( from the chi-square table)
For =
= 2.700 ( from the chi-square table)
Hence, = 19.023 and
= 2.700
