According to data from the Environmental Protection Agency,the average daily water consumption for a household of four people in the United States is approximately at least 243 gallons.(Source: http://www.catskillcenter.org/programs/csp/H20/Lesson3/house3.htm)Suppose a state agency plans to test this claim using an alpha level equal to 0.05 and a random sample of 100 households with four people. State the appropriate null and alternative hypotheses. A)H₀: μ > 243 H_a: μ ≤ 243 B)H₀: μ < 243 H_a: μ ≥ 243 C)H₀: μ ≤ 243 H_a: μ > 243 D)H₀: μ ≥ 243 H_a: μ < 243

Quizplus · Accepted Answer

The null hypothesis (H0) should reflect the claim being tested, which is that the average daily water consumption is at least 243 gallons. Therefore, H0: μ ≥ 243. The alternative hypothesis (Ha) is the opposite, suggesting that the average is less than 243 gallons, Ha: μ < 243.
