QUESTION 5 Ten samples of an oxide of nominally the same mass are heated in an oxygen-rich atmosphere for 1 hour. The mass of each sample increases by an amount shown in the table below. Mass gain (mg) 9.7 11.4 10.3 10.9 10.5 11.0 10.4 11.2 11.3 12.0 Verify that the mean of the values is 10.87 mg and that the unbiased sample variance is 0.436 mg². Using this data, calculate the estimated uncertainty in the mean of the mass gain (in mg) to two decimal places.
