A company claims that the mean monthly residential electricity consumption in a certain region is more than 870
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 900 kWh. Assume the population standard deviation is 121 kWh. At a = 0.05, can you
support the claim? Complete parts (a) through (e).
