A company claims that the mean monthly residential electricity consumption in a certain region is more than 860 kilowatt-hours (kWh). You want to test this claim. You find that a random sample of 70 residential customers has a mean monthly consumption of 880 kWh. Assume the population standard deviation is 130 kWh. At a = 0.01, can you support the claim? Complete parts (a) through (e). (a) Identify Ho and H₂. Choose the correct answer below. OA. Ho: μ>860 (claim) Ha:μ≤860 OC. Ho: μ≤880 Ha: > 880 (claim) OB. Ho: μ = 880 Ha: μ#880 (claim) O D. Ho: μ> 880 (claim) Ha:μ≤880
