a H0 15 n 10 0 01 b H1 0 62 n 27 0 01 c H1 14 4 n 21 0 05 Use Table A 4 to find the critical values of x2 based on the given information

Question: a. H0: = 15 n = 10 = 0.01 b. H1: > 0.62 n = 27 = 0.01 c. H1:

a. H0: σ = 15
n = 10
α = 0.01
b. H1: σ > 0.62
n = 27
α = 0.01
c. H1: σ < 14.4
n = 21
α = 0.05
Use Table A-4 to find the critical values of x2 based on the given information.
