Question
video gamer believes that team composition greatly affects win rate. 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 particular two-player game starts with a pile of diamonds and a pile of rubies. Onyour turn, you can take any number of diamonds, or any number of rubies, or an equalnumber of each. You must take at least one gem on each of your turns. Whoever takesthe last gem wins the game. For example, in a game that starts with 5 diamonds and10 rubies, a game could look like: you take 2 diamonds, then your opponent takes 7rubies, then you take 3 diamonds and 3 rubies to win the game.You get to choose the starting number of diamonds and rubies, and whether you gofirst or second. Find all starting configurations (including who goes first) with 8 gemswhere you are guaranteed to win. If you have to let your opponent go first, what arethe starting configurations of gems where you are guaranteed to win? If you can’t findall such configurations, describe the ones you do find and any patterns you see.arrow_forwardYou and your team have built a chess computer. To investigate how well it performs, you organise a tournament with 100 randomly selected grandmasters (a title given to expert chess players by the world chess organization FIDE), where your computer will play each of the grandmasters once, and it is recorded whether the game is a win for the computer, a win for the grandmaster, or a draw. 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. 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. Two members of your team make claims about the new version of the computer. Alice claims that the new version will perform better against grandmasters than the previous version. Bob claims that the new version will score an average…arrow_forwardSalma publishes a blog on bird-watching, with field notes and pictures of her trips around the country.

- the comic book store owner is curious in how well radio and newspaper advertisements work. A sample of 22 counties with almost equal populations was gathered during the month. For each of the counties, the owner has set aside a particular sum for radio and newspaper advertising. Additionally, the owner was able to access comic book sales information for the stores he controlled in each municipality and classified it as Low or High.

Consumers were asked to decide which of two sodas, Brand 1 or Brand 2, they preferred. The manufacturer was interested in determining what factors played a role in people's taste preferences. One of the factors studied was which part of New Zealand the consumers lived in, and for this purpose the manufacturer divided consumers into South Islanders and North Islanders. If the true consumer population proportion of North Islanders who prefer Brand 1 is pN and the true consumer population proportion of South Islanders who prefer Brand 1 is pS, what null and alternative hypotheses should be used to test whether a larger proportion of North Islander consumers than South Islander consumers prefer Brand 1? ] Select one: a.H0 : pN - pS > 0, Ha : pN - pS = 0 b.H0 : pN - pS = 0, Ha : pN - pS ≠ 0 c.H0 : pN - pS = 0, Ha : pN - pS ≥ 0 d.H0 : pN - pS = 0, Ha : pN - pS > 0arrow_forwardMy neighborhood has a lot of dogs. In fact, when I walk my dog, Wrigley, only 2% of the time do we not see any other dogs. Gary has three dogs (Salsa, Nacho, and Dublin), and we see only Gary and his dogs about 30% of the time when we are on a walk. Lesley has two dogs (Buster and Oreo), and we see only Lesley and her dogs 20% of the time when we are on a walk. Gary and Lesley’s dogs don’t get along; we never see them at the same time. Margo has one dog (Bond), and we see only Margo and Bond 25% of the time when we are on a walk. 10% of the time we see Margo and Lesley. What is the probability that Wrigley and I see both Gary (Salsa, Nacho and Dublin) and Margo (Bond) on a walk? What is the probability we see at least one dog owner on our walk? What is the probability we see only Margo or only Gary? Are the events seeing Gary and seeing Margo independent? EXPLAIN briefly. Are the events of seeing Lesley and seeing Gary mutually exclusive? EXPLAIN briefly.arrow_forward
- This game is called “Get Negative”. Roll two dice (record these in the order you roll them), and then do then do the following: take the first number rolled and subtract 2 times the second number rolled. Regardless of who rolls, Player A gets 3 points if the product is greater than or equal to 0 (i.e. it is zero or positive); Otherwise Player B gets 1 points. The players may or may not take turns rolling the dice as it does not matter who is rolling. Any player may score on any roll, and every roll will result in a score. Play the game by rolling the dice 25 times. For each turn, keep a record of both dice and the resulting answer and the points scored, according to the rules above. Tally the points and calculate the final score for each player. Remember, someone gets a point for each turn, depending on the numbers rolled. (One does not have to be rolling to receive the points.) (Note: you may test the game by yourself by doing all of the 25 rolls yourself and just giving the…arrow_forwardBasketball players can take shots worth 333 points, 222 points, or 111 point. A scout is assessing two players—Tabitha and Lauren—who play for different teams in different leagues. The scout wonders if they have similar or different shot selections. They take a random sample of Tabitha's games and a separate random sample of Lauren's games. They tally how many of each type of shot the players attempted in those games. Here is a summary and the results of a chi-square test: Chi-square test: Shot vs. player Tabitha Lauren 333-point 888 121212 Expected 10.3410.3410, point, 34 9.669.669, point, 66 222-point 404040 373737 Expected 39.8339.8339, point, 83 37.1737.1737, point, 17 111-point 121212 777 Expected 9.839.839, point, 83 9.179.179, point, 17 �2=2.097, DF=2, P-value=0.350χ2=2.097, DF=2, P-value=0.350\chi, squared, equals, 2, point, 097, comma, start text, space, D, F, end text, equals, 2, comma, start text, space, P, negative, v, a, l, u, e, end text,…arrow_forwardResearch study comparing alcohol use for college students in the United States and Canada reports that more Canadian students drink but American students drink more.

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?
