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
H_A : μ > 100

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 H_A : μ > 100

Quizplus · Accepted Answer

The null hypothesis (H₀) represents the claim that the mean battery life is 100 hours or less, while the alternative hypothesis (Hₐ) represents the claim that the mean battery life is greater than 100 hours, which aligns with the company's claim.
