AN American roulette wheel contains, 38 slots: 18 red, 18 black, and 2 green. A casino has purchased a new wheel and they want to know if there is any evidence that the wheel is unfair. They spin the wheel 100 times and it lands on red 44 times, black 49 times, and green 7 times. Do a chi- square testing (goodness of fit) to see if we have sufficient evidence at 5% that the proportions are what is expected or not.
