Q5. A random sample of 8 apparently healthy x 15 | 14 | 12 | 11 |9 | 8 6 5 children between the ages of 5 years and 15 years Y 45 35 32 28 26 27 24 18 yielded the following data. Where 'X' represents the age (in years) and 'Y' represents the liver volume per units of body weight (ml/kg). Using SPSS Software investigate the relation between X and Y: (i). Plot the data into the Scatter diagram. From the diagram write, the result whether it indicates positive or negative correlation? Why? (ii). Write the correlation coefficient of X and Y, also interpret its strength of correlation value? (iii). Write the linear regression equation, which describes the true relationship between the dependent variable Y and the independent variable X.
