Answer now please

Oxygen analyzer is used to analyze the Oxygen content in the flue gas which is coming out from the Boiler's chimney. The O2 analyzer reading for boilers A, B, and C were 21 %, 17%, 19 % by volume, respectively. Repeated measurements of oxygen percentages in the exhaust gas for the three boilers were performed. The results are shown in the following table: BOILER (A) BOILER(B) BOILER (C) 16.63 22.03 20.56 20.83 21.65 19.43 16.75 16.62 16.66 16.64 19.05 18.99 19.04 18.96 19.02 a) Determine the sample mean and standard deviations for the three samples b) Which of the samples do you think is more precise? Why? c) Which of the samples do you think is more accurate? Why
