Psychologists conduct a study to see if right-handed people have a greater tendency to turn right. In the study, 220 right-handed people are sent down an unfamiliar hallway that offers the possibility of turning left, turning right, or continuing straight. They are told that each direction will take them to the desired destination. It is postulated that right-handed people will turn right 75% of the time, turn left 5% of the time, and go straight 20% of the time. In the experiment, 165 of the people turn right, 11 turn left, and 44 go straight. Conduct aχ2 goodness-of-fit test to see if the data provide sufficient evidence to refute the postulated percentages. Select the appropriate critical value (CV), test statistic (TS), and decision. (Useα= 0.05.)


CV = 5.9915, TS = 0.00, fail to rejectH0; handedness does not seem to affect which way people turn



CV = 5.9915, TS = 353.1, rejectH0; handedness does seem to affect which way people turn



CV = 7.8147, TS = 353.1, rejectH0; handedness does seem to affect which way people turn



CV = 5.9915, TS = 1.225, fail to rejectH0; handedness does not seem to affect which way people turn
