Unformatted text preview: Where is the true value? In a replicate analysis, the carbohydrate content of a glycoprotein is found to be 12.6, 11.9, 13.0, 12.7, 12.5 g of carbohydrate per 100 g protein. Find the 50 and 90 % confidence intervals for the carbohydrate content. 1) Calculate the average and standard deviation. 2) Determine the confidence intervals. To be determined in class Grams of nitrogen rich gas isolated by Lord Rayleigh From Air From Chemical Decomposition 2.31017 2.30143 2.30986 2.29890 2.31010 2.29816 2.31001 2.30182 2.31024 2.29869 2.31010 2.29849 2.31028 2.29889 Avg.= 2.31010 2.29947 s= +/ 0.0014 +/ 0.00137 Is the mass of nitrogen isolated from dry air different from the mass of the same volume of nitrogen isolated from chemical decomposition of N 2 O? Lord Rayleigh postulated that these should be the same if dry air was composed of only one fifth oxygen and fourfifths nitrogen. So he compared their densities (measured the masses of equal volumes of gas)....
