Chi-Square and F-Distribution Exam
Portage Learning Math 110
Question 1
Find the value of \( \chi^2 \) for 17 degrees of freedom and an area of \( 0.005 \) in the right
tail.
Calculation: From the chi-square table:
Look across the top for \( 0.005 \).
Look down the left column for \( 17 \).
\( \chi^2 = 35.718 \)
Answer: \( \chi^2 = 35.718 \)
Question 2
Find the value of \( \chi^2 \) for 10 degrees of freedom and an area of \( 0.005 \) in the left tail.
Calculation:
Area in the left tail = \( 0.005 \).
Convert to right tail: \( 1 - 0.005 = 0.995 \).
From the table: \( \chi^2 = 2.156 \).
Answer: \( \chi^2 = 2.156 \)
