10) The following results were obtained in an analysis of iron content in an ore sample. The results reported as % Fe for each analysis, were as follow: Samples no. % Fe 1 3 4 20.10 20.50 18.65 19.25 19.40 19.99 i. Calculate the mean and median from the set of the data above ii. If the true value of %Fe is 19.65 %, calculate the value for absolute error and percentage relative error for sample no. 3 Using Q-test, justify whether an of the data must be rejected at 95 % i. confidence level iv. Calculate the standard deviation and relative standard deviation of the data.
