Question: Use software to find the probability (a) 2 17.2 when d.f. = 9. (b) 2 > 13.7 when d.f. = 23. (c)

Use software to find the probability
(a) χ² ≤ 17.2 when d.f. = 9.
(b) χ² > 13.7 when d.f. = 23.
(c) Find c such that P(χ² > c) = .015 when d.f. = 12.
(d) Find c such that P(χ² < c) = .04 when d.f. = 33.
