(Time: 1 hour only) Q1 (a) The total students at a large university is more than 25,000. The student height data follow normal distribution with mean height of 1.625 meter and standard deviation of 0.075 meter. A random sample of 36 students is selected. Compute the probability that the average height is greater than 1.65 meter. ( 8 marks ) µ´ x = µ = 1.625 (1 mark) σ´ x = σx / n = 0.075 / 36 = 0.0125 (2 marks) P(´ x > 1.65 ) = P ( Z > 1.65 1.625 0.0125 ) (2 marks) = P ( Z > 2 ) (1 mark) = 0.02275 (2 marks) GOOD LUCK UNIVERSITI TUN HUSSEIN ONN MALAYSIA Faculty of Mdechanical & Manufacturing Engindedering...
