1. In a chemical distillation process, a study is conducted to find a relationship between the percentage of hydrocarbons that are present in the main condenser of the distillation unit and the percentage of the purity of oxygen produced. The data is shown as follows. Hydrocarbon (%) 0.99 1.02 1.15 1.29 1.46 1.36 0.87 1.23 Oxygen Purity (%) 90.01 89.05 91.43 93.74 96.73 94.45 87.59 91.77 (a) Identify the independent and dependent variables (b) Test the linearity between x and y at 95% confidence interval using t-test
