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 69 residential customers has a mean monthly consumption of 880 kWh. Assume the population standard deviation is 120 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: H≤ 880 Ha: μ> 880 (claim) C. Ho: 5860 Ha: μ> 860 (claim) OE. Ho: μ>860 (claim) H₂: HS860 B. Ho: >880 (claim) H₂: H≤880 (Round to two decimal places as needed.) OA. The critical values are t OB. The critical value is OD. Ho: H=860 (claim) H₂: H860 OF. Ho: H=880 Ha: *880 (claim) (b) Find the critical value(s) and identify the rejection region(s). Select the correct choice below and fill in the answer box within your choice. Use technology.
