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 four 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 a = 0.2 hour. Uge 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? P- Value = Blank 1 Is there evidence to support the claim that mean battery life exceeds 4 hours? Blank 2 Blank 1 Add your answer Blank 2 Add your answer

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 four
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. Uge 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?
P- Value = Blank 1
Is there evidence to support the claim that mean battery life exceeds 4 hours? Blank 2
