Question

For d f = 5 and the constant A, identify the value of A such that

a. P(x² > A) = 0.90
b. P(x² > A) = 0.10
c. P(x² > A) = 0.95
d. P(x² > A) = 0.05
e. P(x² < A) = 0.975
f. P(x² < A) = 0.025

Answer 1

Similarly, look up α=0.1, or cumulative probability = 0.9, df=5, A=9.24.

You could find (b) and (c) in a similar way.
