The Farm Program for the Montana State Department of Agriculture needs to choose a sample of farms in order to collect information about land utilization. Montana has 56 counties and the 26,800 farms across the state are currently categorized by county. The program would like to select a random sample of at least 112 farms and record the total acreage and the acreage used for pasture and range for each farm in the sample. Two plans have been proposed: Plan A: The program will randomly select 10 counties from the 56 counties. All farms within the 10 selected counties will be visited by a surveyor who will calculate the total acreage and acreage used for pasture and range. Plan B: The program will randomly select 2 farms from each county. All 112 selected farms will be visited by a surveyor who will calculate the total acreage and acreage used for pasture and range. Which of the following best describes the…
