The desired percentage of SiO₂ in a certain type of aluminous cement is 5.5. To test whether the true average percentage is 5.5 for a particular production facility, 16 independently obtained samples are analyzed. Suppose that the percentage of SiO2 in a sample is normally distributed with = 0.32 and that x = 5.24. (Use α = 0.05.) (a) Does this indicate conclusively that the true average percentage differs from 5.5? State the appropriate null and alternative hypotheses. OH: μ = 5.5 Ha: μ< 5.5 O Ho: μ = 5.5 Ha: μ ≥ 5.5 O Ho: μ = 5.5 H₂:μ # 5.5 O Ho: μ = 5.5 Hg: μ > 5.5
