#1: Cornelia Cornwallis,a co-owner ofCorning Cornfields, is concerned about some bugs blighting her bread and butter corn crop.She wants to sample selected ears of corn to check for insect infestation.The fields where the bread and butter corn stalks are growingare naturally split into five corn patches: north, south, east, west, and central.However,she simply walks over to the south patch which is closest to heroffice;sheinspectsthe first few dozen corn stalks she finds as she walks into that particular patch, then calls it a day and heads back.Whatonesampling techniquebestmatches this scenario?

#5: Cornelius Cornwallis,a co-owner ofCorning Cornfields, is worried bugs are blighting all their corn crops,not just the bi-color, yellow and white corn Cornelia treasures as bread and butter.He plans to select randomly a varying number ofears of corn,based on percentages of the totalcrop, according toa variety of overlapping descriptors.He hopes to select some stalks that were dosed with extra organic insecticidesdue to overt damage from bugs eating those stalks, as well as stalks from various areas that flooded when border streams overflowed.Some sampled stalks may unfortunately have fit both categories.He will also select ears with white kernels from patches with either white corn plus yellow and white; he will furtherselect ears with yellow kernels from patches with yellow, or yellow and white corn.Fortunately, Cornelia heard about his sampling frame and convinced him to scrap it as ineffective.Indeed, it is not a particularly recommended sampling technique.Whatonesampling techniquebestmatches this scenario?

#8: Cornelia Cornwallis,a co-owner ofCorning Cornfields, is concerned about some bugs blighting her bread and butter corn crop.She decides to expand her sampling beyond her own corn patches.She asks a neighboring corn farmer what percentage of her bread and butter corn is infested with insects;she then ask that bread and butter corn farmer for a referral.That next farmer provides the data and makes yet another referral.The process continues in this linearmanner, one farmer and corn patch at a time, until she ascertains the number of data points she seeks.Whatonesampling techniquebestmatches this scenario?
