In a yogurt filling line, the containers are filled with yogurt. The producer uses a scale with anaccuracy of 1,8 percent of its range of 9 kg to measure the mass of each container in order to calculate theuncertainty in mass of the containers. 19 containers are selected at random and measured. The averagemass is 2 kg, and the standard deviation of the measurements is calculated to be 0,89 kg. Calculate the total uncertainty of the average mass of the containers at a 95 % confidence level.
