Suppose you have a random sample from a N(μ,σ2) distribution with σ2 unknown. Let n = 10. Consider testing H0 : μ = 13 versus HA : μ ?= 13. Suppose you observe x ¯ = 11.7 and s2 = 3.71. Consider testing this hypothesis by using confidence intervals. Do you reject H0 at α = 0.10?, at α = 0.05?, at α = 0.01?
