The residents of Flint, Michigan are hoping to show that lead in the pipes is lowering the IQ of children in the city and need to have a statistician give evidence at the p<.05 level to do so. They have a psychologist randomly administer IQ tests to 200 children in the town and they find the average IQ of those children is 98. The IQ of children in general is known to have a mean of 100 with a standard deviation of 15.

1. Restate the question:

   • Population 1:

   • Population 2:

   • Research hypothesis:

   • Null hypothesis:

   • Determine the characteristics of the comparison distribution to compare to sample distribution:

     • μ 1 (Population 1):

     • N (Population 1):

     • μ2 (Population 2):

     • σ2(Population 2):

     • μ2M (Population 2, distribution of means):

     • σ2M (Population 2, distribution of means):

     • Is the distribution of means normally distributed?

     • Why does the distribution of means have a normal distribution, a non-normal distribution, or an unknown distribution?

     • c. Determine the critical value (cutoff score) on the comparison distribution at which the null hypothesis should be rejected

     • Determine the Z score of your sample

     • Decide whether to reject the null hypothesis

     • State the findings in term of the study

     • Calculate the 95% confidence interval for what the true IQ is of children in Flint.

You are working the day shift on a medical inpatient unit. You are discussing discharge instructions with
J.B., an 86-year-old man who was admitted for mitral valve repair. His serum blood glucose had been
averaging 250 mg/dL or higher for the past several months. During this admission, his dosage of insulin
was adjusted and he was given additional education in managing his diet. While you are giving these
instructions, J.B. tells you his wife died 9 months ago. He becomes tearful when telling you about that loss
and the loneliness he has been feeling. He tells you he just doesn't feel good lately, feels sad much of the
time, and hasn't been involved in his normal activities. He has few friends left in the community because
most of them have passed away. He has a daughter in town, but she is busy with her work and grandchildren.
He tells you that he has been feeling so down the past few months that he has had thoughts about
suicide.

Please help me write SBAR for this case study

The Situation At the board meeting, you give your financial report. You actually have a small profit to show for the month on the income statement, but as you are going over that report in the board packet, you notice that all six board members have already turned past the income statement to the accounts receivable report. One board member actually has his mouth open, jaw dropped, and another is looking at you over his glasses. This is not good. Your board members are community representatives; they care about the hospital, and they know how important the hospital is to the town of 35,000 people. They are all very worried. They know what has happened to other communities when their hospitals have failed financially. Everyone in this room has a tremendous stake in the survival and success of the hospital. After you give the accounts receivable report, there is a prolonged silence. You wish somebody would just yell at you and get it over with, but that does not happen. -Come up with a plan to bring AR days back in line. It will take cooperation from the medical staff, the clinical departments, health information management, the business office, and many others, so include how you will involve these departments in devising a solution.

Chrysler Concorde: Acceleration Consumer reports stated that the mean time for a Chrysler Concorde to go from 0 to 60 miles per hour was 8.7 seconds.

a.) If you want to set up a statistical test to challenge the claim of 8.7 seconds, what would you use for the null hypothesis?

b.) The town of Leadville, Colorado, has an elevation over 10,000 feet. Suppose you wanted to test the claim that the average time to accelerate from 0 to 60 miles per hour is longer in Leadville (because of less oxygen). What would you use as an alternative hypothesis?

c.) Suppose a newer model year Chrysler Concorde came out and you wanted to test whether the average time to accelerate from 0 to 60 miles per hour had changed from the previous year. What would you use as an alternative hypothesis?

d.) Suppose you made an engine modification and you think the average time to accelerate from 0 to 60 miles per hour is reduced. What would you use as an alternative hypothesis?

e.) For each of the tests in parts (b), (c), and (d) , would the P-value area be on the left, on the right, or on both sides of the mean?

The case studies in your course text Operations Management: An Integrated Approach offer glimpses into the real world of business operations, allowing for deeper analysis of issues related to operations management, budgeting, and business strategy.

Read the case "Hightone Electronics, Inc.," which begins on page 24 of your text. Then respond to case questions 1 and 2 on page 25.

Case: Hightone Electronics, Inc.

George Gonzales, operations director of Hightone Electronics, Inc. (HEI), sat quietly at the conference table overlooking the lobby of the corporate head-quarters office in Palo Alto, California. He reflected on the board meeting that had just adjourned and the challenge that lay ahead for him. The board had just announced their decision to start an Internet-based division of HEI. Web-based purchasing in the electronics industry had been growing rapidly. The board felt that HEI needed to offer on-line purchasing to its customers in order to maintain its competitive position. The board looked to George to outline the key operations management decisions that needed to be addressed in creating a successful Internet-based business. The next board meeting was just a week away. He had his work cut out for him.
Hightone Electronics, Inc. was founded in Palo Alto, California over 50 years ago. Originally, the company provided radio components to small repair shops. Products were offered for sale through a catalog that was mailed to prospective customers every four months. The company built its reputation on high quality and service. As time passed, HEI began supplying more than just radio parts, adding items such as fuses, transformers, computers, and electrical testing equipment. The expansion of the product line had been coupled with an increase in the number and type of customers the company served. Although the traditional repair shops still remained a part of the company's market, technical schools, universities, and well-known corporations in the Silicon Valley were added to the list of customers.

Today HEI operates the Palo Alto facility with the same dedication to supplying quality products through catalog sales that it had when it was first founded. Customer service remains the top priority. HEI stocks and sells over 22,000 different items. Most customers receive their orders within 48 hours, and all components are warranted for a full year.

Expanding HEI to include Web-based purchasing seems to be a natural extension of catalog sales that the company already does successfully. George Gonzales agrees that the company has no choice but to move in this competitive direction. However, George does not agree with the opinion of the board that this would be "business as usual." He believes that there are many operations decisions that need to be identified and addressed. As he stated in the meeting, "Having a slick Web site is one thing, but making sure the right product is delivered to the right location is another. Operations is the key to making this happen." His challenge for the next board meeting was to identify the key operations decisions and persuade the board that these issues needed serious consideration.

Case Questions

1. Explain why operations management is critical to the success of a business. Why would developing an Internet-based business require different operations considerations for HEI? Is George Gonzales correct in his assessment that this would not be "business as usual"?

2. Recall that HEI wishes to continue its reputation of high quality and service. Identify key operations management decisions that need to be considered. How different will these decisions be for the Internet business?

Joe operates a business that locates and purchases specialized assets for clients, among other activities. Joe uses the accrual method of accounting but he doesn’t keep any significant inventories of the specialized assets that he sells. Joe reported the following financial information for his business activities during year 0.

Determine the effect of each of the following transactions on the taxable business income.

Required:

1. Joe has signed a contract to sell gadgets to the city. The contract provides that sales of gadgets are dependent upon a test sample of gadgets operating successfully. In December, Joe delivers $11,550 worth of gadgets to the city that will be tested in March. Joe purchased the gadgets especially for this contract and paid $8,550.
2. Joe paid $185 for entertaining a visiting out-of-town client. The client didn’t discuss business with Joe during this visit, but Joe wants to maintain good relations to encourage additional business next year.
3. On November 1, Joe paid $410 for premiums providing for $41,000 of “key man” insurance on the life of Joe’s accountant over the next 12 months.
4. At the end of year 0, Joe’s business reports $9,150 of accounts receivable. Based upon past experience, Joe believes that at least $2,030 of his new receivables will be uncollectible.
5. In December of year 0, Joe rented equipment to complete a large job. Joe paid $3,150 in December because the rental agency required a minimum rental of three months ($1,050 per month). Joe completed the job before year-end, but he returned the equipment at the end of the lease.
6. Joe hired a new sales representative as an employee and sent her to Dallas for a week to contact prospective out-of-state clients. Joe ended up reimbursing his employee $310 for airfare, $360 for lodging, and $260 for meals $160 (Joe provided adequate documentation to substantiate the business purpose for the meals). Joe requires the employee to account for all expenditures in order to be reimbursed.
7. Joe uses his BMW (a personal auto) to travel to and from his residence to his factory. However, he switches to a business vehicle if he needs to travel after he reaches the factory. Last month, the business vehicle broke down and he was forced to use the BMW both to travel to and from the factory and to visit work sites. He drove 125 miles visiting work sites and 48 miles driving to and from the factory from his home. Joe uses the standard mileage rate to determine his auto-related business expenses.
8. Joe paid a visit to his parents in Dallas over the Christmas holidays. While he was in the city, Joe spent $55 to attend a half-day business symposium. Joe paid $210 for airfare, $54 for meals during the symposium, and $23 on cab fare to the symposium.

  (For all the transactions, select "No Effect" from the dropdown if no change in the taxable business income and for part g, round your answer to whole number. Use standard mileage rate.)
