nathan and jordan design surveys to determine the average amount of time bicyclists in a race spend training each week. nathan surveys every fifth bicyclist crossing the finish line after a race. jordan surveys the first five bicyclists to finish the race. which best explains which sample is likely to be the most valid?\n\nnathans because his sample was more random\njordans because his sample was more random\nnathans because his sample contained elements of the population\njordans because his sample contained elements of the population
Answer
# Brief Explanations:
A valid sample should be random to accurately represent the population. Nathan surveys every fifth bicyclist crossing the finish - line, which is a form of systematic random sampling. Jordan surveys the first five bicyclists, which is a convenience sample and may be biased (e.g., the first five could be the most dedicated or fastest cyclists with different training patterns). Random samples are more likely to be representative of the entire population of bicyclists in terms of training time.
# Answer:
A. Nathan's because his sample was more random
