Use the standard normal distribution or the? t-distribution to construct a 90 confidence interval for the population mean. Justify your decision. If neither distribution can be? used, explain why. Interpret the results. In a recent? season, the population standard deviation of the yards per carry for all running backs was 1.37. The yards per carry of 25 randomly selected running backs are shown below. Assume the yards per carry are normally distributed.

2.4 4.5 3.6 5.3 4.8 6.8 5.9 4.9 4.9 1.7 2.1 6.4 4.5 5.1 4.1 7.4 6.9 4.4 6.8 6.6 4.8 7.1 6.1 7.2 6.6

Which distribution should be used to construct the confidence? interval?

A. Use a? t-distribution because nless than<30 and ? is unknown.

B. Use a normal distribution because n less than n<30?, the miles per gallon are normally distributed and ? is unknown.

C. Use a? t-distribution because nless than<30 and ? is known.

D. Use a normal distribution because sigma? is known and the data are normally distributed.

E. Cannot use the standard normal distribution or the? t-distribution because sigma? is? unknown, n less than n<30?, and the yards are not normally distributed.

Select the correct choice below? and, if? necessary, fill in any answer boxes to complete your choice.

A. The 90% confidence interval is ?(?). ?(Round to two decimal places as? needed.)

B. Neither distribution can be used to construct the confidence interval.

Interpret the results. Choose the correct answer below.

A. With 90?% ?confidence, it can be said that the population mean yards per carry is between the bounds of the confidence interval.

B. If a large sample of players are taken approximately 90?% of them will have yards per carry between the bounds of the confidence interval.

C. It can be said that 90?% of players have a yards per carry between the bounds of the confidence interval.

D. Neither distribution can be used to construct the confidence interval.

you are provided with four scenarios. For each scenario, you are required to answer the following question:

What are the access-to-care issues in the given situations? Suggest at least two solutions to address the access-to-care issues in these scenarios.

Scenarios:

Mr. A is a 30-year-old African American male. His employer provides for his health insurance, which covers emergency room visits, hospitalization, and some preventive-care services such as yearly physicals. Whenever he schedules appointments for preventive-care services, he has to spend one to three hours at the doctor's office. Additionally, he has to schedule follow-up appointments for laboratory tests after each office visit.

Mrs. B is a 30-year-old African American woman with two children. She is employed at a workplace that does not provide the employees with health insurance. Mrs. B and her children make frequent visits to the emergency room for healthcare services.

Mr. C is an unemployed 52-year-old Asian male who has not seen a doctor in at least eight years. He speaks limited English. He has been experiencing some health problems. He was recently told about a free clinic located within a couple of miles of his apartment. There are no Asian healthcare providers at the local health clinic. He has some concerns about healthcare provided by anyone other than Asian healthcare providers.

Mrs. D and her husband, a middle-aged Caucasian couple, recently moved to a rural community. They are both on medications for chronic health conditions, which require them to go for bimonthly doctor visits. Their car recently broke down and there is limited bus service in their community. They are having a difficult time going for their appointments and obtaining their medications. They are also less motivated to seek care because they have some major disagreements with the primary care doctor who is a young woman in her early thirties.

Munch N’ Crunch Snack Company is considering two possible investments: a delivery truck or a bagging machine. The delivery truck would cost $53,252.28 and could be used to deliver an additional 47,000 bags of pretzels per year. Each bag of pretzels can be sold for a contribution margin of $0.38. The delivery truck operating expenses, excluding depreciation, are $0.52 per mile for 16,000 miles per year. The bagging machine would replace an old bagging machine, and its net investment cost would be $54,765. The new machine would require three fewer hours of direct labor per day. Direct labor is $15 per hour. There are 250 operating days in the year. Both the truck and the bagging machine are estimated to have seven-year lives. The minimum rate of return is 9%. However, Munch N’ Crunch has funds to invest in only one of the projects.

a. Compute the internal rate of return for each investment. Use the above table of present value of an annuity of $1. If required, round your present value factor answers to three decimal places and internal rate of return to the nearest percent.

Third time asking this question. Please read the question fully and answer it fully as well. Thank you.

You are an ethnobotanist conducting a study with the Yagua Indians of the north Peruvian Amazon. After working with your study communities for a year, you have documented the medicinal use of more than 200 plant species and have both collected vouchers and taken copious notes on how the plants are prepared and used. Unfortunately, you have also noted some threats to the persistence of both the medicinal plant traditions and the ecosystem itself:
•    Of the communities studied (total population: 900 people), only 6 elderly people had extensive knowledge of medicinal plants in the area and the younger generations knew of the uses of the 10 most popular medicinals.
•    There are signs of loggers cutting down forests just 50 miles south of the traditional Yagua land. If the loggers continue north, they will encroach on the Yagua traditional hunting grounds and sacred forest sites, where many of the medicinal plants are collected.
•    The Peruvian government has installed a small health post in a neighboring village and many people are abandoning the use of traditional remedies in favor of the medicines provided at the health post.
•    One of the most popular medicinal plants still used by the Yagua is also being collected for sale to passing river barges that take it to market in the city. Over collection of the plant is threatening its survival in the region.

In order to promote the protection of both the traditional ecological knowledge and plants of this region, you need to design a conservation action plan to present to the Yagua council of elders. In your action plan, you need to present detailed strategies that will help them to conserve their traditions and plants, addressing the four issues listed above. Explain both your role and their role in these conservation efforts. Use examples from your reading and video assignments to back up your argument.

Grading rubric
•    Present solution for each issue (4 points)
•    Overall rationale and feasibility of your action plan (3 points)
•    Use of examples from your reading and video assignments to strengthen your argument (3 points)

For this assignment you are provided with four scenarios. For each scenario, you are required to answer the following question:

O RECEIVE CREDIT, YOUR ORIGINAL POST MUST BE MADE AT LEAST 24 HOURS BEFORE THE DROP BOX CLOSES TO ENABLE YOUR CLASSMATES ADEQUATE TIME TO MAKE RESPONSES. You should post an ORIGINAL RESPONSE to ONLY ONE of the following discussion questions (minimum of 2 paragraphs - 10 points) and RESPOND to TWO other posts (minimum of 1 paragraph - 5 points each). Your original post must be substantiated with AT LEAST TWO topics discussed in the related chapter (include the page number(s) in parentheses within your post). Your responses must consist of more "meat" than 'I agree', or 'Good point.' All discussion posts will be evaluated on content, not just completion. Be specific and be thorough. The posts are a significant part of your class grade. 1. The chapter discusses the practice of serial wardrobing, where people return an outfit after they wear it for a special occasion such as a formal. What do you think of this practice? Is it okay to use an expensive product once and then get your money back? 2. Today many consumers pursue a ‘decluttering lifestyle.’ Should marketers encourage this trend toward simplicity even though it stresses buying less stuff that marketers sell? What marketing opportunities do you foresee if this trend spreads? Support your comments. 3. Car owners can now let insurance companies monitor their driving using new technology in exchange for lower rates. For example, customers who sign up for Progressive’s TripSense program get a device the size of a Tic Tac box to plug into their cars. The device will track speed and how many miles are driven at what times of day. Every few months, customers unplug the device from the car, plug it into a computer, download the data, and send them to the company. Depending on results, discounts will range from 5 to 25 percent. Would you be willing to give up personal privacy in exchange for lower prices? Support your opinion.

The nature of lake is that there is a giant explosion of what are called “midges” in the mid to late summer. If you haven’t been around and seen these bugs:

Your car gets covered so bad that you can’t see out the windsheild after driving 10 miles! They get everywhere; don’t open your door at night as they flood in! Now althought this is seen as a menace from bug hell, there are some not so obvious advantages which come from this menace. Who see the bugs, catch them and feed them to their young. And Who “see” bugs through sonar,their voices are their “eyes and ears”.

Professor from the Environmental program is trying to get an estimate of the population of bats that are around the lake to quantify the relationship and population dynamics of bats to the severity of the menace. Now bats are night creatures you see, well he can’t see so well as it is night! He is at a conundrum for how to measure the number of bats in a given area. Very difficult to do as you can’t visually (unless you have a light, yet this will probably throw off the count of bats as the bugs are attracted to the light, hence bats also, yet this would lead to an unnatural or not normal distribution of bats!) so he must be away from the street lights further down the road and the lights from cars with that blasting stereo to drowned out the new street performance muffler shouldn’t affect the natural distribution of bats. The second issue is that bats don’t fly in formation, they come from all directions almost randomly. Prof. has come to you for a solution to his bat count problem. Using the knowledge you have gained, come up with a simple design to help Prof. count his bats. Describe your solution and reasons why you chose this solution. Include any calculations and a concluding paragraph of what you have learned in this problem.
