Question

When a battery company claims that their batteries last longer than 100 hours and a consumer group wants to test this claim, the hypotheses should be: H0 : μ ≤ 100 HA : μ > 100

The null hypothesis (H0) represents the status quo or claim to be tested, which is that the mean battery life is 100 hours or less. The alternative hypothesis (HA) represents the claim that the consumer group wants to test, which is that the mean battery life is greater than 100 hours.
