For a statistics project, Tony decided to investigate if students at his school prefer name brand potato chips to store-brand potato chips. He prepared two identical bowls of chips, filling one with name-brand chips and the other with store brand chips. Then, he selected a random sample of 50 students, had each student try both types of chips in random order, and recorded which type of chip each student preferred. Assume that 40% of students at Zenon’s school prefer the name-brand chips. Let X = the number of students in the sample that prefer the name-brand chips.
