ou and your team have built a chess computer. Tlo investigate how well it performs, ou organise a tournament with 100 randomly selected grandmasters (a title given to xpert chess players by the world chess organization FIDE), where your computer will lay each of the grandmasters once, and it is recorded whether the game is a win for the omputer, a win for the grandmaster, or a draw. For each win against a grandmaster, he computer scores 1 point, and for each draw the computer scores half a point. At the nd of the tournament, the chess computer has scored 60 points.

To test this idea, the player decides to play 100 matches with teams of 3 colors: Red, Green, and Blue. The player records the number of matches he wins with each team color. Given anecdotal evidence, the gamer believes his red team is the best and therefore will win the most games. He has less experience with his blue and green team and is interested to see if there is a difference between the two. Because the gamer is more experienced with his red team, he plays more matches with that team. The total number of matches played per team color is: Red-50, Blue-23, and Green 27. a) What is the IV of this experiment? What are the levels of the IV? What is the scale of measurement of the IV? b) What is the DV of this experiment? What is the scale of measurement of the DV? c) Is this a True experiment or not? Explain your reasoning. d) What is the hypothesis of this experiment? Is it directional or nondirectional? e)…A schoolteacher is concerned that her students watch more TV than the average American child. She reads that according to the American Academy of Pediatrics (AAP), the average American child in the population watches 4 hours of TV per day. She records the number of hours of TV that each of her six students watches per day. The times (in hours) are 4.5, 2.5, 5.5, 3.0, 5.0, and 4.0. a. Test the hypothesis that her students watch more TV than the average American child in the population. Use a=.01. Use the four steps of hypothesis testing.

For each win against a grandmaster, the computer scores 1 point, and for each draw the computer scores half a point. At the end of the tournament, the chess computer has scored 60 points. i) Identify the population, sample and sample size. ii) Identify a reasonable parameter and parameter space. iii) Using the results of the tournament, give an estimate of the parameter. Explain whether this is an unbiased estimate. Subsequently, you and your team go away to improve the chess computer. After a while, you organise another tournament, where the computer will again play 100 randomly selected grandmasters.…Aidan is a goalie for his school’s hockey team. He normally stops 87% of the shots that come his way. In one particularly bad game, he let five of the 15 shots into the goal. He decides to cheer himself up by convincing himself that this game would be unusual for a goalie who stops 87% of the shots. He uses the table of random digits below using the rule that he will read across the row, two digits at a time, with 01–87 indicating a stop and 88–99 and 00 indicating a goal, until 15 attempts are recorded. 61373 70629 96541 81508 28214 06485 Which of the following statements about this random number table best describes the simulation?

- An experiment is designed to see whether 3rd graders can write faster with a pen or pencil. Four third graders participate, 2 boys and 2 girls. For each child, a marble is drawn without replacement from a bucket containing 2 red marbles and 2 blue marbles. If a red marble is selected, the child gets a pen and if blue, the child gets a pencil. The children are assigned in this order: boy 1, girl 1, boy 2, girl 2. LetX be the number of boys assigned to a pen. Find E (X). Find SD(X). а. b.One hundred extremely intelligent male prisoners are imprisoned in solitary cells and on death row. Each cell is soundproofed and completely windowless. There is a separate room with one hundred small boxes numbered and labeled from 1 to 100. Inside each of these boxes is a slip of paper with one of the prisoners' names on it. Each prisoner's name only appears once and is in only one of the one hundred boxes. The warden decides he is going to play a game with all of the prisoners. If they win, they will all be let free, but if they lose the game, they will all be immediately executed. The hundred prisoners are allowed to enter this separate room with 100 boxes in any predetermined order they wish, but each can only enter the room once and the game ends as soon as the hundredth person enters the room. (At any time, only one prisoner is allowed to enter and remain in this room.) Once a prisoner enters the room, he is allowed to open and look inside as many as Xboxes, where X is a…there is a factory that makes widgets in different colors. The production time for each color is different. At the end of each day, all the widgets produced that day are placed in boxes. On a certain day, the factory made 1,620 yellow widgets and 5,760 pink widgets. It takes 18 minutes to produce a batch of yellow widgets and 40 minutes to produce a batch of pink widgets. Determine the largest number of widgets that can be placed in each box if it is required that all boxes contain the same number of widgets and each box contains only one color. Explain the steps and problem-solving strategy used to determine the answer E. Determine the largest number of widgets that can be placed in each box if it is required that all boxes contain the same number of widgets and each box contains only one color. Explain the steps and problem-solving strategy used to determine the answer. 1. Explain why the final answer is a greatest common divisor, least common multiple, or neither
