Researchers have long known that people feel lonely when they are ostracized by other people. A researcher wonders if being ostracized by a computer also makes people feel lonely. To test this hypothesis, the researcher recruits 18 people to participate in a study and measures their current feelings of loneliness using the Social Loneliness Scale (SLS). This scale yields scores between 0 and 11, with higher scores meaning greater feelings of loneliness. The SLS scores form an interval scale that is normally distributed. After completing the pretest measure of loneliness, the participants play a game called Cyberball. In the game, participants simply play catch with computer-generated players. The participants in the study know that the players in the game are computer controlled and are not controlled by human players. When participants begin the game, the computer-generated players pass the ball back and forth with each other and with the participant. After 30 throws, the computer-generated players stop passing the ball to the participant. This exclusion (i. e., ostracism) continues for 20 passes before the games end. After playing the game, all participants complete the SLS again. What is the one-tailed research hypothesis for this study
