Medicаl reseаrchers hаve develоped a new artificial heart cоnstructed primarily оf titanium and plastic. The heart will last and operate almost indefinitely once it is implanted in the patient's body, but the battery pack needs to be recharged about every 4.5 hours. A random sample of 36 battery packs is selected and subjected to a life test. The average life of these batteries is 4.027 hours. Assume that battery life is normally distributed with standard deviation σ= 0.24 hour. Is there evidence to support the claim that mean battery life fails to meet the stated life? Use α= 0.01
