The desired percentage of Sio,, 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 obtaine are analyzed. Suppose that the percentage of Sio, in a sample is normally distributed with o = 0.32 and that x = 5.22. (Use a = 0.05.) (a) Does this indicate conclusively that the true average percentage differs from 5.5? State the appropriate null and alternative hypotheses. Ο H: μ= 5.5 HạiH < 5.5 O Ho: H = 5.5 Hai H2 5.5 O Ho: u = 5.5 Hi H#5.5 O Hai 4 = 5.5
