Question:

A certain process for removing copper from copper bearing ore had been in use for a period of time, and it is known that this process removes 36 pounds per ton on average. A new process that is supposed to increase the recovered amount is being tested. In a simple random sample of 100 batches of ore, an average of 42 pounds per ton were recovered using the new process. The population of interest in the study is: O The increase of 6 pounds per ton. O The miners working with the ore. O The 100 batches tested. O Ore treated with the new process. O Ore treated with the old process
