What steps can be taken to protect intellectual property (both domestically and internationally)? In business, do you feel the best defense is a good offense? In other words, in constant innovation and improvement more important than intellectual property protection measures? Explain your reasoning.

Please explain how to solve using RStudio, if possible.

In a experiment on relaxation techniques, subject's brain signals were measured before and after the relaxation exercises with the following results:

Is there sufficient evidence to suggest that the relaxation exercise slowed the brain waves? Assume the population is normally distributed. Select the test statistic, p­-value, Decision to Reject (RH₀) or Failure to Reject (FRH₀)].

Numerical data, measured in quantitative terms, reveal trends and patterns over time. For, example testing a new fall-prevention program within your hospital would require you to obtain a baseline fall rate before the program and then again after implementation of the program. Statistically, you could compare rate of falls before the new program with the rate of falls after the new program.

The demand function for a commodity is described in terms of an equation:
Px = -Qdx + 35, while the offering function Px = 0.5Qsx + 3. Taxes are subject to 30$ of the commodity. Determine also if the government provides
subsidy of 2$ for each unit of goods

a. What is the equilibrium price and the equilibrium quantity that occurs in the market
b. What is the equilibrium price and the equilibrium quantity before tax?
c. What is the equilibrium price and the equilibrium quantity after tax?
d. What is the equilibrium price and the equilibrium quantity before and after there are subsidies

The owner of a large apartment complex had an in-ground swimming pool installed in an effort to increase tenant satisfaction. Nine tenants were randomly selected to complete a questionaire that assessed their level of satisfaction with the apartment complex. Their scores before and after the installation of the pool are taken (before -after). The owner wants to assess the effectiveness of the pool in increasing tenant satisfaction.

a) state the hypothesis in symbols

b) indicate the type of t-test ( one sample two sample or paired?)

c) indicate if it is an observational study /survey or an experiment.

Use the Wilcoxon matched-pairs signed rank test to determine whether there is a significant difference between the related populations represented by the data below. Assume a 5% level of significance and (differences = before - after).

Before    After
5.6        6.4
1.3        1.5
4.7        4.6
3.8        4.3
2.4        2.1
5.5        6.0
5.1        5.2
4.6        4.5

Using the table of Critical Values, what is the critical value for this study?

1. The journal entry to record sale of repurchased stock is:

2. Describe the impact of a treasury stock transaction on total shareholder’s equity.

3. Explain why companies issue stock splits

---- Using a textbook example, compare the line items in equity before and after a stock split:

Before After

Split Split

Stockholders’ equity

Paid-in capital

Common stock, $10 par

Paid-in capital in excess of par value

Total paid-in capital

Retained earnings

Total stockholders’ equity

Outstanding shares

To test the effect of a physical-fitness course on one’s physical ability, the number of sit-ups that a person could do in 1 minute, both before and after the course, was recorded. Six randomly selected participants scored as shown below. Can we conclude that a significant amount of improvement took place? Use α = 0.01 and assume normality. (Please show all steps of classical approach.)

Before 29 22 25 29 26 24

After 30 26 25 35 33 36

A scientist claims that pneumonia causes weight loss in mice. The table shows the weights​ (in grams) of six mice before infection and two days after infection. At

alphaαequals=0.050.05​,

is there enough evidence to support the​ scientist's claim? Assume the samples are random and​ dependent, and the population is normally distributed. Complete parts​ (a) through​ (e) below.

Due to less business at many car repair workshops during lockdown, some of the workshops had to lay off a number of employees. People were mostly working from home and they were not using their cars. John was among the people that were retrenched. The industry consultants reckon it could take them a while before the business can peak.

John decided to set his own backyard business at home where he could serve the people in his neighbourhood. He then realised that for him to be able to make a viable business, he has to order genuine parts form recognised dealers for the types of cars that he will be working on. The suppliers have computerised their systems and some of the suppliers have closed warehouses where he cannot go and select the motor parts.

John must make his orders online from the car parts suppliers. Besides repairing cars, John also sells parts to other mechanics in the area who are not able to buy from the car parts dealers. John’s clients order the car parts and online. John’s company uses a delivery service to get the car parts to the respective clients who would have ordered online. John uses social media and word of mouth to advertise the businesses.

Suppliers of different car parts deliver the products to his home. He receives different types of delivery notes. Some suppliers send hard copies and some send the delivery notes to be signed online when the order arrives. There are clients from the neighbourhood that can order online and make a payment when they go to John’s house to collect their orders. Source: Makhurane, N. (2020)
