A quality control engineer is testing the battery life of a new smartphone. The company is advertising that the battery lasts 24 hours on a full charge (HO), but the engineer suspects that the battery life is actually less than that (HO). They take a random sample of these phones to see if their average battery life is significantly less than 24 hours. Let Ml represent the mean battery life for this population of phones (example from Khan Academy). With a standard deviation of 2 and an alpha=0.05, can you reject this claim
