MO22. Medical researchers have developed a new artificial heart constructed primarily of 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 our hours. A random sample of 50 battery packs is selected and subjected to a life test. The average life of these batteries is 4.05 hours. Assume that battery life is normally distributed with standard deviation o = 0.2 hour. Use a = 0.05. What is the P-value (4 decimal places i.e., 0.0000) and is there evidence to support the claim that mean battery life exceeds 4 hours?
