question 4

Essay

Game Wizard A friend of yours is constantly bragging that he performs exceptionally well at a popular video game since he scores an average of 1400 points. You think he is not all that hot. Having taken a statistics class, you know that you can actually test to see whether or not your friend scores higher than other players of the game. You collect a random sample of scores from other players at the local arcade and get the following data:
1375 1420 1250 1310 1450 1380 1390 1410 1290 1360
Is your friend right? That is, is there evidence that other players average less than 1400 points per game? Conduct a hypothesis test, making sure to state your conclusion in context of the problem.
