Several years ago, many scientists got together to explore the effect that newly released, violent video games had on adolescents. They setup a scenario where a group of adolescents was assigned to either puzzle games or first player shooter games. The victor of the game was then given the choice to "punish" the other players by celebrating with either an airhorn or a cowbell. The aggression was determined by the length of time the victor employed their celebratory "weapon" of choice. This is a observational or experimental The population of this study is .

For a recent evening at a small, old-fashioned movie theater, 40% of the moviegoers were female and 60% were male. There were two movies playing that evening. One was a romantic comedy, and the other was a World War II film. As might be expected, among the females the romantic comedy was more popular than the war film: 70% of the females attended the romantic comedy. Among the male moviegoers the romantic comedy also was more popular: 65% of the males attended the romantic comedy. No moviegoer attended both movies. Let F denote the event that a randomly chosen moviegoer (at the small theater that evening) was female and F denote the event that a randomly chosen moviegoer was male. Let R denote the event that a randomly chosen moviegoer attended the romantic comedy and R denote the event that a randomly chosen moviegoer attended the war film. Fill in the probabilities to complete the tree diagram below, and then answer the question that follows. Do not round any of your responses. (If…
A few years ago, a cola manufacturer invited New Zealand consumers to take a blind taste test. 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 > 0
My 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.
A 20-sided die is often used in tabletop role-playing games like Dungeons and Dragons. During the game players may face something called a "skill check" where they must roll a 20-sided die and get a result equal to or above a given value. For example, a player may be required to roll a 15 or above in order to succeed and pass the skill check. Rolling a 14 or lower would be a failure. If the player rolls the die 10 times in a row, what is the expected number of rolls that would pass the skill check by rolling as a 15 or higher? For the previous calculations, what is the standard deviation for the number of times the die would be rolled 15 or above?Round your answer to 2 decimal places.During a game of Dungeons and Dragons, the previously-mentioned player rolls the 20-sided die 30 times in total. What is the probablity that they successfully roll a 15 or higher exactly 7 times during that game? Express your final answer as a percentage to 2 decimal places. The probability…
In a cooking competition called Heaven's Kitchen, two teams compete against each other to serve a restaurant full of customers. The competitors cook dishes and send them to an executive chef, where it is either approved and sent to the customer, or is deemed unacceptable and sent back to the kitchen. The competition has run for the past 19 years. During the 9th annual Heaven's Kitchen competition, the Ruby team cooked a total of 124 dishes, of which 50 were sent back to the kitchen by the executive chef. In the same period, the competing Sapphire team cooked a total of 154 dishes and had 56 return. Construct a confidence interval to estimate the difference in the proportion of dishes sent back to the Ruby team and the proportion of dishes sent back to the Sapphire team. Use a confidence level of 93%. Round each answer to 4 decimal places. Do not round from one part to the next when performing the calculations, though. Find the confidence interval. <p1−p2<
Traditionally, the game of Rock, Paper, Scissors is played with two people. Each of the two people, on the count of 3, reveals their hand in the shape of a rock, a piece of paper, or a pair of scissors as best they can (usually with a closed fist, a flat hand, or their index and middle fingers outstretched to form the V of an open pair of scissors). As the rules go, rock smashes scissors, paper covers rock, and scissors cuts paper. The game can be extended to an arbitrarily large number of, say, nn people, where nn is greater than or equal to 2. If when all nn people reveal their play and only 1 or all 3 options appear, that round is deemed indecisiveindecisive and they just play again. If when all nn people reveal their play precisely two of the three options appear, that round is decisivedecisive, and those with the winning play continue while those with the losing play are eliminated. Play continues until only one person remains. Assume the game begins with nn players, each of whom…
A health scientist is testing the effectiveness of three different diets (Diet A, Diet B, and Diet C). To determine diet effectiveness, a group of 72 participants were weighed and then randomly assigned to adhere to one of the three diets for a month (N = 24 for each group). At the end of the month, each participant was weighed again and the amount of weight lost was calculated in kilograms (kg). Using the variables “Diet” and “Weight Loss kg”, conduct a One-Way, Between Subjects, ANOVA, at α = 0.05, AND conduct Tukey's Post Hoc testing to find out which of the three diets was most effective. Identify the correct symbolic notation for the alternative hypothesis. A. HA: µ1 ≠ µ2 ≠ µ3 B. H0: µ1 = µ2 C. H0: µ1 = µ2 = µ3 D. HA: µ1 ≠ µ2

Let’s say a psychologist suspects that emotions affect people’s eating habits, but that the eating habits of anxious people are affected differently. Ten highly anxious subjects are randomly divided into two equal-sized groups, one of which views a horror movie while the other watches a comedy. Ten non-anxious control subjects are similarly divided. The number of ounces of popcorn eaten by each subject during the movie is recorded. How many independent variables are there in this design? Name each of the factors and levels (using appropriate descriptors from the paragraph): How many total conditions (groups) are there in this design? Name the dependent variable:
jared is opening several ice cream stores. The walls of the stores can be yellow or blue. He wants to determine if the color of the walls affects how much ice cream people eat. Jared finds 164 volunteers. He randomly assigns half of them to a room with yellow walls and lets them eat as much chocolate ice cream as they want for one hour. He assigns the other half to a room with blue walls and lets them eat as much vanilla ice cream as they want for two hours. Jared records the total amount of ice cream eaten in each room.Which would be an appropriate statistical model for Jared to use in order to determine if the color of the wall affects how much ice cream his customer will eat?
In a study carried out among low-income families in the young towns of Detroit, it was found that 30% spent less than $8 weekly on purchasing charcoal and consumed products from soup kitchens. 35% spent $8 to $15 weekly on the purchase of charcoal. 5% spent more than $15 weekly on the purchase of charcoal and consumed products from the soup kitchen. 15% spent more than $15 each week buying coal. Finally, 55% did not consume the products of the soup kitchens.If you randomly choose a low-income familyto. What is the probability that you spend less than $8 weekly on purchasing coal?b.
