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 66 residential customers has a mean monthly consumption of 900 kWh. Assume the population standard deviation is 123 kWh. At α = 0.10, can you support the claim? Complete parts (a) through (e).(a) Identify \( H_0 \) and \( H_a \). Choose the correct answer below.- A. \( H_0: \mu = 860 \) (claim) \( H_a: \mu \neq 860 \) - B. \( H_0: \mu > 900 \) (claim) \( H_a: \mu \leq 900 \)- C. \( H_0: \mu = 900 \) \( H_a: \mu \neq 900 \) (claim)- D. \( H_0: \mu \leq 860 \) \( H_a: \mu > 860 \) (claim)- E. \( H_0: \mu \leq 900 \) \( H_a: \mu > 900 \) (claim)- F. \( H_0: \mu > 860 \) (claim) \( H_a: \mu \leq 860 \)
