Texts: Q4 (@) Based on your understanding, state the differences of the following terms. (i) Null and alternative hypothesis (2 marks) Type I and Type II error (2 marks) (ii) (b) According to the Kementerian Kesihatan Malaysia (KKM), the mean height of Malaysian adults ages 20 and older is about 66.5 inches (69.3 inches for males, 63.8 inches for females). In our sample data, we have a sample of 408 college students from a single college. Using SPSS output in Table Q4 (One-Sample Test), test if the mean height of college students at this college is significantly different than 66.5 inches at a=0.05. Table Q4 Test Value = 66.5 Mean 95% Confidence Interval of the Difference Significance One-Sided Two-Sided Lower Upper af a a < < Height 1.531 1.1035 2.0501 5.81 407 .001 001 (Inches) (7 marks) (c) The following data is about the average mileage recorded by two engines. The sample mean for engine type I is 14 with a sample standard deviation of 1.6. For engine type II, the sample mean is 23 with a sample standard deviation of 1.7. Test the hypothesis using a level of significance of 0.025. The average mileage for engine type I is lower than the average mileage for engine type II. Assume that the variances are unknown but equal. (9 marks)

HC?CH CH?CO?H H?SO? HgSO? Acetylene Acetic Acid H?C=C?O?C=O?CH? Vinyl acetate Acetylene reacts with acetic acid in the presence of H?SO? and HgSO? to yield vinyl acetate, a monomer used in the production of poly(vinyl acetate). The reaction mechanism includes the following steps: 1. Formation of a bridged mercurinium ion intermediate between Hg²? and acetylene; 2. Addition of acetic acid to open the three-membered ring; 3. Proton transfer to solvent to give an organomercury vinyl ester; 4. Addition of H? to the alkene to form a carbocation; 5. Expulsion of Hg²? to form the alkene. Diagram the mechanism on a separate sheet of paper, and then draw the structure of the product(s) of step 4. • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Draw organic species only. • Do not include counter-ions, e.g., Na?, I?, in your answer.
