The following table shows the data for the exerted pressure and the corresponding volume of a particular gas. Pressure 1015 2000 3000 4000 5000 6000 Volume 1000 505 330 255 205 170 The relationship between the pressure exerted by the compressed gas and the volume of the gas based on the above set of data is given by V = -0.1466P + 924.1250 where P is the pressure (in hPa) and V is the volume (in mL). (i) What is the volume of the gas if the pressure is 4875 hPa? Comment on the reliability of the answer. (3 marks) (ii) Given that the correlation coefficient is r = -0.8765, interpret this value. (2 marks) (iii) Calculate the coefficient of determination and interpret the value.
