(b) Find the critical value χ²(16, 0.10).


(c) Find the critical value χ²(20, 0.90).


(d) Find the critical value χ²(13, 0.995).

(e) Calculate the value for the test statistic, χ², for H_o: σ² = 19.6, n = 18, s² = 16.7.
χ²* =  

(f) Calculate the value for the test statistic, χ², for H_o: σ² = 29.3, n = 23, s = 6.3.
χ²* =  

(g) Calculate the value for the test statistic, χ², for H_o: σ = 41.8, n = 12, s = 38.1.
χ²* =  

(h) Calculate the value for the test statistic, χ², for H_o: σ = 13.8, n = 26, s² = 164.
χ²* =
