Air crew escape systems are powered by a solid propellant. the burning rate of this propellant is an important product characteristic. specifications require that the mean burning rate must be 50 centimeters per second. the experimenter selects a random sample of n=40 and obtains an observed sample mean of the burning rate 51.3 centimeters per second and an observed sample standard deviation of the burning rate 2.0 centimeters per second. based on a 5% type i error threshold, construct a hypothesis test and draw your conclusion.
