) The U.S. Census Bureau computes quarterly vacancy and homeownership rates by state and metropolitan statistical areas. The following data are the rental vacancy rates in percentage (%) grouped by region for the first quarter of 2019 using a sample of 4 statistical metropolitan areas.

Vacancy rates (%)

Region Northeast South West
1 6 12 8

2 5 9 10

3 9 11 8

4 4 8 6

Sample Mean Sample   6 10 8

Variance 4.7 3.3 2.7

a.(10pt) Perform an ANOVA test to find if there are vacancy rates differences among the regions. Allow 1% error on your test.

b. (5pt) Do you think that the mean vacancy rate is the same for these regions? Why?

One way to implement a queue is to use a circular linked list. In a circular linked list, the last node’s next pointer points at the first node. Assume the list does not contain a header and that we can maintain, at most, one iterator corresponding to a node in the list. For which of the following representations can all basic queue operations be performed in constant worst time? Justify your answers. Maintain an iterator that corresponds to the first item in the list. Maintain an iterator that corresponds to the last item in the list.

A university system enrolling thousands of students needs to determine how many credit hours, on the average, each student takes per quarter. From previous studies, the population standard deviation is known to be 2.3 credit hours per quarter. Suppose the administration wanted to estimate the mean to within 0.1 hours with 95% confidence. How large a sample would they need to take?

IGM Realty had stock prices of $33, $33, $38, $36, and $28 at the end of the last five quarters respectively. If IGM pays a dividend of $1.1 at the end of each quarter, what is the annual realized return on IGM?

Set up an amortization schedule that amortizes $500,000 with 5 years of cyclical quarterly payments. The annual interest rate is 6%. The payment schedule is: " one-third a normal payment" at the end of quarter 1, "normal payments" at the end of quarters 2 and 3, and "50% of a normal payment" at the end of quarter 4.

please solve in excel and list equations that go in the cells. Thank you :)

Heads or Tails

A few things for this discussion board: 1. You do not need to post first for this board. 2. You do NOT need to respond to other posts. 3. You DO need to answer all the questions below to get full credit.

1. Obtain a quarter coin. Flip the coin 10 times. Record your results.

2. Summarize YOUR results in terms of heads and tails.

3. Calculate the probability of heads and tails from your results.

4. Combine your results to the previous results posted. (I want a running total of all results.)

5. Calculate the probability of heads and tails from the discussion total thus far. (If you are the first post, you will not have other results to combine with - that's okay).

6. Discuss what the difference (if any) between your results and the class combined results.

7. What do you expect the probability to be as more and more students post?

Here is an example (do no include this in your total).

Shannon flips a quarter 10 times, I get the following results:

1. T H H T T T T H T T

2. 7 Tails 3 Heads

3. P(Tails) = 0.70   P(Heads) = 0.30  

4. Combine my results (Let's assume so far there are 33 Heads and 27 Tails) Now we would have 36 Heads and 34 Tails

5. P(Heads) = 36/70 = 0.514 P(Tails) = 34/70 = 0.486.

6. My results were slightly different than the class summary. I had a higher probability of tails and a lower probability of heads.

7. You will need to do this in your own words.

The Public Health Directorate in November 2015 anticipated the outbreak of Yellow Fever in the first quarter of the ensuing year 2016. The Directorate subsequently asked the procurement officer to place an order for the supply of Yellow Fever vaccines.

In December, 2015, the Procurement officer placed an order for the supply of the vaccines but the order was silent on the strengths of the vaccine and delivery date. In January 2016, the Head of Entity requested the Procurement Officer to brief him on the preparedness towards the anticipated outbreak. The procurement officer confirmed placing an order in December 2015 for the supply of the vaccines. Delivery was expected in the first quarter of 2016 before the anticipated outbreak. In February 2016, the Procurement Officer got anxious that the vaccines had not been delivered as expected. Sporadic cases of Yellow Fever were reported in endemic districts in the Asempa region of Ghana.

The Head of Entity convened a meeting to discuss the outbreak. Public Health practitioners in the Region confirmed their preparedness through treatment protocols to support fieldwork in the event of an epidemic. It became obvious that the delivery could not be made before the outbreak. The Head of Entity accordingly requested the Procurement Officer to brief the meeting on arrangements made for the delivery of the vaccines.

In response, the Procurement Officer presented volumes of files in support of orders placed. It took the meeting three sittings to retrieve a copy of the particular contract.

When the supplier was contacted to explain the delivery, he intimated that he had an unlimited time for delivery as the contract was not explicit on the delivery date. He however informed the entity that he had pediatric doses of the vaccine which he could immediately supply

Eventually there was an outbreak which claimed several lives. The Procurement Officer insisted that he was not blamable because he had placed the order as far back as December, 2015.

Q.Can the use of emerging technologies used in supply chain management help to avert such situations?

Tangshang Industries production budget from the 2^nd quarter of 2018, projected the following amounts of units to be produced:

April    1,000 units

May     1,200 units

June     1,250 units

Each unit requires 2 parts of component A and 3 parts of component B. Component A cost is $1.25 per unit and component B cost is $.80 per unit.

Each unit requires the following labor:

2 hours in the processing department

1 hour in the assembly department

Processing department labor rate is $4/hour

Assembly department labor rate is $6/hour

Variable Factory overhead is $.60 per unit

Fixed Factory overhead is $1,000 monthly

Using the information from the production budget of Tangshang Industries

1.Calculate total variable overhead cost for May 2018

2.Calculate total variable overhead cost for the quarter April - June 2018

3.Calculate total overhead cost for the quarter April - June 2018

4.Calculate total product cost for the quarter April - June 2018

Prepare a sales, production, direct materials, direct labor, overhead, and selling & administrative expense budget by quarter for the year 2020 for the Budgets R Us Co. using the following assumptions:

1. Sales quantity by quarter: 10,000, 11,000, 12,000, 13,000, 14,000, 15,000.
2. Selling price per unit = $20.
3. Ending FG inventory = 10%.
4. RM pounds per unit = 4.
5. Ending RM inventory = 20%.
6. RM price per pound = $2
7. Direct labor hours per unit = 2
8. Direct labor hourly rate = $20.
9. Variable overhead costs per direct labor hour: Indirect labor = $1.60, Indirect material = $.40, Maintenance = $.70, Repairs = $.30.
10. Fixed overhead costs per quarter: Depreciation = $20,000, Supervisor’s salary = $10,000, Rent = $5,000.
11. Variable selling & administrative costs: Sales commission = 5% of sales dollars, Packaging & shipping = $2 per unit sold.
12. Fixed selling & administrative costs per quarter: Sales salaries = $30,000, Insurance = $5,000, Advertising = $15,000.

Moonbeam Company manufactures toasters. For the first 8 months of 2020, the company reported the following operating results while operating at 75% of plant capacity:

Cost of goods sold was 70% variable and 30% fixed; operating expenses were 80% variable and 20% fixed.

In September, Moonbeam receives a special order for 15,000 toasters at $7.50 each from Luna Company of Ciudad Juarez. Acceptance of the order would result in an additional $2,900 of shipping costs but no increase in fixed costs.
