Although still a sophomore at college, John O'Hagan's son Billy-Sean has already created several commercial video games and is currently working on his most ambitious project to date: a game called K that purports to be a "simulation of the world." John O'Hagan has decided to set aside some office space for Billy-Sean against the northern wall in the headquarters penthouse. The construction of the partition will cost $8 per foot for the south wall and $12 per foot for the east and west walls. What are the dimensions of the office space with the largest area that can be provided for Billy-Sean with a budget of $384? What is the south wall length ft? What is the east and west wall length ft? What is its area in ft2?

A chef is trying out a new recipe he has been working on and wants to see if it will sell better than his old one. To find out, he performs an experiment where he randomly assigns 20 people to try his new recipe and 20 people to try his old one. He asks each group how much they would be willing to pay for their food, and he finds that the group with the old recipe would pay an average of $20.00 and the second would pay an average of $26.00. He then performs an independent samples t-test between these groups. a. Suppose the sample variance for the price of the chef’s old recipe is $2.00, and the sample variance for the new recipe is $3.00. Perform a one-tailed t-test at a significance level of α = 0.01 and explain what the result means (how does the new recipe compare to the old one?). b. To evaluate the magnitude of effect size, compute the estimated Cohen’s d. Briefly describe what it means, and comment on the strength of the effect: is it weak, moderate or strong?
Joe and Maggie take turns mowing the lawn each week. Maggie suggests they try a new system for determining who should mow the lawn. Each week, they will roll two dice and determine the sum of the values. Since the highest possible sum is 12, Maggie will mow the lawn if the sum is 6 or less, and Joe will mow the lawn if the sum is greater than 6. Before agreeing to Maggie's suggestion, Joe wants to check if this plan would be fair. He decides to roll a pair of dice and determine the sum of the values 100 times. The graph shows the results of the 100 trials. Based on his simulation, should Joe agree to Maggie’s plan? (yes/no), because a sum greater than 6 is likely to occur (more than, less then, equal to)(30%, 50%, 75%) of the time
Kabaddi is a popular sport in South Asia. The basic rules of Kabaddi are simple: two teams of seven players each face off in a large square arena for two halves of twenty minutes each. Players from each team take turns running across the center line to the other team's half of the court ( called "raiding"), tagging members of the other team (4 people defending), and running back. The more opposing team members they tag, the more points they score (+1 point for each player he tags), but if the opposing team can physically prevent them from crossing back to their side of the court, they score no points. During the sports week, a kabaddi match is going to be scheduled between the students of Section A and C. Section A has 42 students while Section C has 35 students
Your school's basketball team is organizing a bus trip to a Toronto Raptors game at the Air Canada Centre. The cost to rent the bus, which can carry up to 52 people, is $380 and the cost of tickets for a group of 20 or more is $29.50 per person. In addition, the team wants to make a $250 profit from this event to help defray the costs of a future tournament. However, the school administration requires that the cost of the trip per person not exceed $45. Is this possible? If so, what is the minimum number of people that must participate in the activity?
