Una mezcla de 100kg de gas cuyo análisis Orsat es el siguiente: 6.4% de CO2, 0.2% de O2, 40% de CO, y 50.8 % de H2 (el resto es N2), se quema con 40% de aire en exceso en un horno. ¿Qué composición porcentual tiene el gas de chimenea?

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
