A tablet advertises that it has an all-day battery. The company
claims that their battery will expectedly last 24 hours. Batteries
of that capacity are assumed to have lives that are normally
distributed with (known) standard deviation equal to 1.25 hours. A
random sample of 10 batteries has a sample average life of 23.2
hours. Answer the following questions.
(a) Using α = 0.05, can you support the claim that battery life
is below 24 hours? Hint: Formulate the problem...
