Example: Propellant Burn Rate

Example: Propellant Burn Rate. Aircrew escape systems are powered by a solid propellant. Specifications require that the mean burn rate must be 50 cm/s. H 0 : ? = 50 10 samples are tested. Definitions. Critical region : range of values for which the null hypothesis is rejected
