2. Explain why we use big-O to compare algorithms.
3. Explain why binary search runs in O(log n) time.
4. Under what conditions is it possible to sort a list in less than O(nlog n) time?
5. List and explain the worst-case and average-case running times for each Vector method below:
(a) insert(iterator here, Object item)

(b) insertAtHead

(c) insertAtTail (aka push back)

(d) get(iterator here)

(e) get(index i)

(f) remove(iterator here)

(g) remove(index i)

CONFIDENCE INTERVAL PROJECT – Day 1

For this project, you’ll be calculating a Confidence Interval for both a Proportion and a Mean. You must first choose a theme for your project. Choose something that you are interested in and passionate about.

THEME: ____________________________________

**For this entire project, we are making the population “people you know.” This will allow you to collect data from anyone!

PROPORTION CONFIDENCE INTERVAL:

Think about a proportion that you wish you knew about all of the people that you know. Fill in the following statement relating to your theme:

I wonder what proportion of people that I know ________________________________??

For example: (have red hair)

(are practicing social distancing)

(watched Game of Thrones)

(think Brad Pitt is a good actor)

If you knew the answer to your above question, would it be a statistic or parameter?

(Circle one)

What symbol would represent its value? ________

MEAN CONFIDENCE INTERVAL

This about an average you wish you knew about all of the people that you know. Fill in the following statement relating to your theme:

I wonder what the average _________________________ is of all of the people I know??

For example: (weight)

(number of CDs owned)

(age)

If you knew the answer to your above question, would it be a statistic or parameter?

(Circle one)

What symbol would represent its value? ________

How is the AICPA Code different from the IFAC Code of Ethics? How are they similar?

Select one section of the AICPA code and describe the guidance provided in that section. How could an accountant use the guidance to more effectively manage his conduct as a business professional? Try to support your explanation with a relevant example.

Many students graduate from college deeply in debt from student loans, credit cards, and so on. Curious about the impact of debt on decisions about the future, a WCU sociologist took a random sample of 401 single students at WCU, classified them by a binary view of gender, and asked, “Would you consider marrying someone who was $25,000 or more in debt?” The results of this survey are shown in the following table. Test at a 1% significance level if men and women responded differently from one another. In other words, are gender and response related?

WOMEN, YES = 125

WOMEN, NO = 59

WOMEN, UNCERTAIN = 21

MEN, YES = 101

MEN, NO = 79

MEN, UNCERTAIN = 16

Determine which type of test is required for each question and clearly state the type of test that is called for. Then, perform all steps of the test. Show the critical value approach and the p-value approach. Explain your conclusions at the end of each test.

Given the following students' test scores (95, 92, 90, 90, 83, 83, 83, 74, 60, and 50), identify the mean, median, mode, range, variance, and standard deviation for the sample. Write a 500-750-word summary and analysis discussing the results of your calculations. State your results for the sample: the mean, median, mode, range, variance, and standard deviation Explain which method is best for this data set. Why? Conduct a one sample T-test and interpret the results (use a population mean of 70). In what situations would this information be useful? Please use SPSS.

4. In a recent poll of 737 adults, 92% said that they do not open unfamiliar emails. Use a 0.01 significance level to test the claim that more than 75% of adults do not open unfamiliar emails.

a. Identify the null and alternative hypothesis.

b. Is the test two-tailed, left-tailed or right-tailed? Explain.

c. What is the test-statistic?

d. What is the p-value?

e. What is the critical value?

f.. What is your decision; Reject or fail to reject the null hypothesis? Explain using the results from part d or e.

g. State the final conclusion which addresses the original claim.

Research and review trends in inflation (CPI), interest rates (short and long term), GDP and employment over the last year. Then read the latest speech by the Federal Reserve and answer the following short essay questions. While this is not a paper, you must still properly cite your answer and write in full sentences.

1. Describe and explain the cause of any inflation (or lack of) over the last year.
2. Describe and explain the trends in unemployment over the last year.
3. Report on the current interest rates. Address the fed funds rate, the ten-year treasury rate and the 30 year treasury rate. Explain how and why they have changed over the last year.
4. Describe and explain the shape of the yield curve. What does the curve tell us about the anticipated future of the economy?
5. What is the Federal Reserve's current view of the general state of the economy? Of employment? Of inflation?
6. What is the current primary concern of the Chairman of the Federal Reserve? How is he addressing that concern?
7. How would you advise the Fed to set interest rates next month? Explain your answer.

a) Explain, in detail what Job Order Costing System of cost accumulation. What kind of businesses could possibly benefit from this costing system? How are the manufacturing and non-manufacturing costs allocated under this system? b) There are various techniques of materials control. Just-In-Time Inventory System is one of them. Discuss how this technique was developed, its features, and the benefits it offers. How a business can prepare itself to adopt this technique. c) Every organization is highly concerned in understanding the efficiency of its employees. Various methods have been developed to address this need. Discuss any four methods of rating employees’ efficiency.
