Answer
$χ2_{0.025} = 45.722$
$χ2_{0.975} = 16.047$
Work Step by Step
Here we have α = 0.05 and n = 30 df = 30 - 1 = 29
Since the test is left tailed, α/2 = 0.025
By using Table-VII, we have:
$χ2_{0.025} = 45.722$
For left tailed test we have, 1- α = 0.975
By using Table-VII, we have:
$χ2_{0.975} = 16.047$
