A study examines whether an enriched vs. normal rearing environment changes social behavior in rats. Two rats from each of eight litters are randomly assigned to an enriched vs standard environment. The scores of their social behavior are assessed by a standard rating scale, and are as follows:
| Litter # | Enriched Environment | Standard Environment | |||
| 1 | 23 | 24 | |||
| 2 | 19 | 26 | |||
| 3 | 26 | 19 | |||
| 4 | 20 | 18 | |||
| 5 | 35 | 30 | |||
| 6 | 40 | 36 | |||
| 7 | 25 | 20 | |||
| 8 | 28 | 21 |
a) Conduct a matched-pair t test to test the null hypothesis that the mean difference in sociability equals 0.
b)The researcher conducted a matched-pair t test because she anticipated that the scores of rats reared in the same litter are not independent of one another. Test this hypothesis by computing the Pearson correlation between the enriched and standard scores and whether it is significantly different from 0.

Given the changes stated, predict new market equilibrium price and quantity demanded. For each question below, show your answer on a well-labeled supply-demand graph.
(a) Housing Market: Price of lumbers has decreased sharply and, at the same time, mortgage rate
has decreased to an all-time low.
(b) Electronics Market: Consumers expect a recession (e.g. a sluggish economy) and, at the same time,
electronics product producers become less productive.
(c) Airline Tickets: A long-cold winter is finally over and hotels and resorts are offering big
discounts.
(d) Automobile: Trade restrictions limit auto companies’ ability to import auto parts.

The following transactions apply to Park Co. for 2016:
1. Received $50,000 cash from the issue of common stock.
2. Purchased inventory on account for $180,000.
3. Sold inventory for $250,000 cash that had cost $140,000. Sales tax was collected at the rate of 5 percent on the inventory sold.
4. Borrowed $50,000 from First State Bank on March 1, 2016. The note had a 7 percent interest rate and a one-year term to maturity.
5. Paid the accounts payable (see transaction 2).
6. Paid the sales tax due on $190,000 of sales. Sales tax on the other $60,000 is not due until after the end of the year.
7. Salaries for the year for the one employee amounted to $46,000. Assume the Social Security tax rate is 6 percent and the Medicare tax rate is 1.5 percent. Federal income tax withheld was $5,300.
8. Paid $5,800 for warranty repairs during the year.
9. Paid $36,000 of other operating expenses during the year.
10. Paid a dividend of $2,000 to the shareholders.
Adjustments:
11. The products sold in transaction 3 were warranted. Park estimated that the warranty cost would be 3 percent of sales.
12. Record the accrued interest at December 31, 2016.
13. Record the accrued payroll tax at December 31, 2016. Assume no payroll taxes have been paid for the year. Do NOT record any federal or state unemployment tax expense or liability.
Prepare an income statement, statement of changes in stockholders’ equity, balance sheet, and statement of cash flows for 2016.

Individuals experience various mood states or emotions at varying times every day, both subtle changes and obvious changes, that can result in attitude alternations with both negative and positive effects and impair or facilitate performance. The connections in the brain between emotion and memory have been particularly interesting to researchers given that neural networks that are activated by mood states are linked with neural networks that process basic perceptual functions such as word processing. Dr. Siebert has conducted a number of research experiments inducing various mood states through the use of music and then studying the effects of mood on lexical processing. (Dr. Pennie S. Siebert)
Research Topic: Mood Induction and Memory
Research Question: How does mood affect cognitive function through neural networks?
1. Develop a null and alternative hypothesis for this research question.
2. Describe the population and sample on which a research project might be based.
3. How would we operationalize the elements we want to test in the research question? What would be the independent and dependent variables?
4. What would be the measurement scale we would use to gather the data?
5. Describe the positive and negative impacts of doing a research project on this topic.

Analyze the county-level population changes in your current state and another state of your choice. Once you have analyzed this data, prepare a business analysis for your manager.
In your analysis, include the following:
Analyze the business issue you are addressing.
Explain the business situation as you understand it.
Identify relevant data (observations and variables) that you will use to address the situation.
Justify your selection of an inferential method to address the business issue.
Explain the inference you wish to make. (Hint: You can estimate, test, or predict. If your selected inference is a prediction, identify what you are trying to predict and what you are basing your prediction on. If your selected inference is an estimate, identify what you are trying to estimate. If your selected inference is a test, identify the claim you are attempting to test.)
Identify the inferential statistical technique that would be the best tool to use for your selected prediction, estimate, or test.
Explain why you believe this would be the best tool for the situation. (Please note that you are not required to compute anything, simply to identify the best tool and explain why.)
Provide examples from your experience and/or from your research to support your selection of inferential statistical technique.

Make following changes. step(A)
step 1 Implementation a Generic Linked List using the program
developed in the class.
step 2 Implement StackImpl class using the generic
linked list.
step 3 Test the program with different type and number of matching
and un-matching brackets.
This is how it works!
When you run the class MatchBrackets a popup dialog appears asking
you to select a file. You are provided two input files in the
project. input1.txt contains matching brackets and input2.txt does
not match the brackets.
You can select any of these files to verify.
Then do steb(B)
step 1 Externalize the inner classes Node and
ListIterator.
step 2 Make the appropriate changes to turn in the LinkedList class
into a generic class.
step3 Use the one exception classes EmptyList where
applicable.
step4 . Implement StackImpl class using the generic linked
list.
step 5 Add test cases in the main method to demonstrate the working
of your code.
. step 6 Run match bracket to check whether the brackets were
matched or not.
