Question 4 (CLO4 - 5 marks] The concentration c of sample A is changing with time t as showed in Table Q4. Determine the concentration at time 90 min by using third and fourth-order polynomials. If the true value of concentration at 90 min is given as 53.25 kg/m3, determine the true error in using both polynomials. Table Q4 65 85 105 125 Time, t (min) Concentration, c(kg/m3) 25 12.43 45 25.14 36.52 49.12 60.41 77.21
