Please answer the following questions. Most of them are multiple choice or short answers.Problem 1 Context The employee manager of a large company would like to estimate the proportion of full-time employees who prefer adopting the basic plan of the available health care plans in the forthcoming annual enrollment period. Given this context, please select the most appropriate answer to each of the following questions. 1) The employee manager believes that if the proportion of employees preferring the basic plan is greater than 17%, then that plan should be subsidized by the company. A 95% confidence interval for the proportion of employees preferring the basic plan yields (16.35%; 18.12%). Based on this interval, at the 5% level of significance what should the manager’s decision be regarding whether or not to subsidy the basic plan? Group of answer choices ( select1)Subsidy the planDo not subsidy the plan Inconclusive. Need more information to make a decision2) Explain your selection on the previous question.3) Write out the null and the alternative hypotheses that the manager is testing in this example.4) The manager is not satisfied with the accuracy of the confidence interval (16.35%; 18.12%). What are the options to increase the interval’s accuracy (at the same confidence level)? (Mark all that correspond) Group of answer choices (choose all that correspond) Increase the sample size Use a smaller multiple (critical value) Use a larger multiple (critical value) Reduce the sample size5) What sample size should they collect to build a 95% confidence interval with a margin of error of 2 percentage points? Use 18% as an estimate for the proportion.Problem 2 ContextA vendor of a software product claims that their new program/app called Algebrawithout Tears greatly enhances the understanding of key mathematical conceptsamong school students. They approached the Anne Arundel County School Districtwith the suggestion that the program be adopted in county schools and integratedinto the curriculum. While the program—which runs on PC/Mac/iPad—has a verynice user interface, it is expensive. There is a $100,000 purchase fee, and an annualmaintenance license cost of $12,000. The county wants to know what the effect ofadopting this program will be on student outcomes. They are aware that somestudents are already using the program (on personal licenses) and collect data fromthree schools. The data is described below:Score: (Dependent Variable) Aggregate score on math exams over the last year (outof 400)Income: Family income in dollarsUse: Whether software has been used for at least 12 months (1 if yes/ 0 if no)School: School attended (identified as A, B, or C)Age: Student age (in years)The categorical variable School, is recoded using two dummy variables (School_A =1 if School = A, and 0 otherwise; School_B = 1 if School = B, and 0 otherwise). Theregression output is given below. ( I have attached it below as exhibit 1) 6) State the multiple regression equation.7) What is the interpretation of the coefficient of Income?8) The p-value for the School_A indicates (please choose the most appropriate answer)9) Should the school district adopt Algebra without Tears and integrate it into the curriculum? Explain.10) What would you expect the math score to be of a girl who is 7 years old, does not use the software in class, goes to school C, and has a family income of $80 thousand? Group of answer choices (choose one below) That School A is not useful explaining Score, given the other variables in the model That School A is a useful predictor That School A provides good math education That School A is statistically different from School BProblem 3 Context: I am Ulysses Uncle Ulysses operates a small business: he produces three types of houses to sell to people wanting to get back to nature. Based on your discussion with your uncle you construct the following table based on your understanding of his weekly availability of labor. Item Profit Fabrication Assembly Painting CratingBirdhouse $15 1 2.5 1 0.25Doghouse $35 1.25 1.5 0.5 0.5Outhouse $58 1.75 4 2 0.75Capacity 30 hours 50 hours 20 hours 20 hoursBased on the information in the table, you formulate the problem as a linear program. The labor needed for fabrication, assembly, painting, and crating is all dedicated solely to each function, i.e., none of the workers have been cross-trained. The Excel sensitivity report is shown below. ( I have attached a screenshot as exhibit 2)11) The optimal production quantities for each product are (round to two decimals): Birdhouses: Doghouses: Outhouses:12) The maximum weekly profit that Uncle Ulysses can make is $ (round to two decimals.)13) Which additional resources would you recommend that Uncle Ulysses try to obtain? (Mark all that correspond) Group of answer choices (select all the correct ones that apply) paint assembly fabrication crate14) Suppose Uncle Ulysses is required by contract with the American Birding Association to make one birdhouse each week. How would this affect his profits?Group of answer choices (select 1)Profits would decrease by $17.15.Profits would increase by $15.Profits would increase by $0.00. Profits would decrease by $1E + 30.15) Uncle Ulysses feels that his prices are too low, particularly for his birdhouses. How much would he have to charge for his birdhouses before it is profitable for him to make and sell them?Group of answer choices (choose 1)$15.00$32.15$47.15 $17.1516)Some kiddos in the neighborhood have started to make and sell their own doghouses. To stay competitive Uncle Ulysses is considering lowering the price of his doghouse, which would reduce the profit per doghouse from $35 to $25. If he does, what would be the effect on this bottom line (total profit)? (select 1 correct answer)It is not possible to say with the information provided. His total profit will stay the same. His total profit will decrease by $153.80. His total profit will decrease by $10. 17) Uncle Ulysses' available hours for crating have fallen from 20 hours to 15 hours because of a new "one-hour nap time" rule for this five-year-old worker. How will this affect his profits?Group of answer choices (select 1 correct answer)Profits will decrease by $7.69.Profits will not change.Profits will increase by $7.69. Profits will decrease by $12.31.18) Uncle Ulysses can obtain an additional 10 hours of painting capacity free of charge by training his helper monkey to paint. If he did this, how would his profits be affected?Group of answer choices (select 1 correct answer)Profit would increase by $6.92.Profits would decrease by $20.Cannot tell from the information provided. Profits would increase by $1.58.19) Uncle Ulysses is planning for next spring, and he is considering making only two products. Based on the results from the linear program, which two products would you recommend that he make?Group of answer choices (Choose 1 correct answer) birdhouses and outhousesdoghouses and outhousesHe should continue to make all three. birdhouses and doghouses20) Your sister is willing to help your uncle with fabrication after school for one hour, three times a week.
