Q2 As a quality control engineer, you are concern about the quality of the produced computer's battery lifespan. In view of this, you have randomly sampled 10 batteries from your production line and recorded the time it took for the battery to completely drained. The collected data are shown in Table Q2 below. Table Q2 Battery lifespan Age of battery (hour) (years) 4.0 1.4 4.2 1.2 4.5 1.0 3.0 2.7 3.8 1.6 3.7 1.8 4.4 1.1 2.3 3.2 2.6 4.1 1.3 3.2 (a) Construct a scatter diagram to represent the relationship between age of battery and its lifespan using graph paper. (b) Assess the relationship between these two parameters by computing the linear regression equation using least square methods. (c) Find the correlation coefficient and coefficient of determinations.
