The Betterbuy Battery Company manufactures alkaline and lithium batteries for use in torches, radios, and other similar devices. They claim that the average operating time of their alkaline batteries is 20.00 hours, with a standard deviation of 1.50 hours. However, a consumer organization believes the average operating time of their alkaline batteries is lower than 20.00 hours. In order to investigate this further, the consumer organization take a random sample of 625 alkaline batteries manufactured by the company during March and tests each battery by putting it in a torch and recording the number of hours it operates for. What is the population we can draw conclusions about in this study?
