Joe wants to find the most common source of news

among U.S. adults. He wants his sample to have
10,000 adults (half male and half female individuals) to
make a valid generalization. How many people from
each of the 50 states should he choose randomly to
avoid bias in his study?

Joe should choose 200 individuals randomly from each of the 50 states in order to avoid bias in his study. This will ensure that his sample is representative of the entire U.S. adult population.
