Atown hosts an arbor day celebration. each of the 105 families attending gets to choose a sapling to take home as they leave. michelle and ari each design surveys in order to determine the average height of the saplings. michelle samples the first 20 families leaving the celebration. ari samples every fifth family leaving the celebration. which best explains which student’s sample is likely to produce more valid results?
michelle’s because she sampled the saplings of every family in her group
michelle’s because she sampled the saplings of the first 20 families to choose their saplings
ari’s because she sampled saplings chosen at different times
ari’s because she sampled one more sapling than michelle sampled
