Document Summary
Coke"s cup is marked with the letter q " and pepsi"s cup is marked with letter m ". Let them choose which cup to drink and do records. Next, pour water into two empty cups and mark one cup with q " and mark another with m " . Then, let the same 200 customers choose which cup to drink and do records. Finally, compare the results, if two results are same, which means people just prefer m " to q " and not related to which drinks they prefer. The customers prefer m " to q " no matter what drinks in cups, the hypothesis is correct; if the first result is different from the second result, which means customers prefer pepsi to coke. Because the household goods are used in daily life in order to increase more opportunities for people to touch: for a common pencil, the input resources usually include wood, lead, metal ring and eraser.
