QUESTION 2 An estimate of a mineral resource using the inverse distance weighting method. Assess the coal data mean values and calculate estimates for point T as shown on the set of coal data below in Table 1. Using the 8 points set of coal data, produce a weighted function for each. Evaluate and conclude on the calculated arithmetic mean (calorific value) and the best estimate of
T
(weighted value) using the eight points. Table 1: Coal data values. \table[[Sample no.,Calorific value,Distance],[,CV,],[1,24.48,155],[2,26.30,164],[3,22.90,213],[4,23.10,345],[5,23.65,320],[6,22.76,330],[7,21.64,223],[8,23.45,325]] [TURN OVER]
