Air crew escape systems are powered by a solid propellant.The burning rate of this propellant is an important productcharacteristic. Specifications require that the mean burningrate must be 50centimeters per second. We know that thestandard deviation of burning rate is σ =2centimeters persecond. The experimenter decides to specify a type I errorprobability or significance level of α=0.05and selects a randomsample of n = 25and obtains a sample average burningrate of x= 51.3centimeters per second. What conclusionsshould be drawn?[
