A random sample of respondents would be distributed randomly, half to the experimental group and half to the control group. A pr

etest questionnaire would be administered to the respondents in both groups to obtain a measurement on attitudes toward Pepsi advertising, brand, and celebrity; only the respondents in the experimental group would be exposed to the TV program containing the Pepsi commercial. Then, a questionnaire would be administered to respondents in both groups to obtain posttest measures on attitudes toward Pepsi advertising, brand, and celebrity. Which of the following experimental design best represents the above scenario?
a. one-shot case study
b. one-group pretest-posttest design
c. after-only with control group design
d. before and after with control group design
e. interrupted time-series design

The experimental design which best represents the above random survey is: B. one-group pretest-posttest design.

An experimental design can be defined as a research method (concept) in which a controlled experimental factor is objectively and efficiently subjected to a special treatment (intervention), in order to compare it with a factor (controlled variable) that is kept constant. Thus, it is used to maximize precision in an experiment and to reach a specific conclusion on a hypothesis statement.

Basically, there are three (3) main types of experimental design and these include:

1. Quasi-experimental research design

2. True experimental research design

3. Pre-experimental research design

Under the pre-experimental research design, we have three (3) forms of experimental design and these are:

  • One-shot case study research design
  • Static-group comparison
  • One-group pretest-posttest design

One-group pretest-posttest research design is mostly used by behavioral researchers to determine the effect of a special treatment (intervention) on a given sample of participants, especially by first utilizing a single group of participants (one-group design) before the treatment is implemented and once after the treatment is implemented.

In conclusion, a one-group pretest-posttest research design is the experimental design which best represents the above random survey.

Westford Corporation has $185 million dollars of interest-bearing debt outstanding at the end of fiscal 2014 year. In addition,
Ratling [72]

Answer:

B) 9.1%

Explanation:

Cost of debt is the interest rate paid by a company due to borrowing money; i.e  debt from investors.

$185million in debt is the face value of debt that Westford Corporation had and the $26 million dollars of interest expense is the cost of the debt in dollars;

First, find pretax cost of debt ;

Pretax cost of debt = (Interest expense / Face value of debt )*100

= (26,000,000/ 185,000,000 )*100

=0.1405 *100

= 14.05%

Next, use pretax cost of debt to find after-tax cost of debt;

After-tax cost of debt = Pretax cost of debt (1-tax)

= 14.05% *(1-0.35)

= 9.13%

Therefore, Westford's cost of debt capital is 9.1%

1. At what level does the supervisor fit in the organizational pyramid? Describe a major trend that is changing the role of the
vredina [299]

Answer:

1. Supervisors fit in the middle level of the organization pyramid.

2. A major trend that is changing the role of the supervisor at that level is the concepts of mentoring, coaching, and staff training.  The supervisor's role is expanding to include these activities that will ensure process improvement, enforce adherence to organization's rules, and enable improved cross-functional relationships.

Explanation:

Primarily, supervisors are known to motivate employees, direct the activities of others, select the most effective communication channel, and resolve conflicts among team members.  However, the changing trend now views the supervisor as an educator, sponsor, coach, counselor, and director.  Therefore, the supervisor is expected to deplore all his skill-sets, including effective communication in combination with daily conflict resolution, transformational leadership, critical thinking, interpersonal relationship, time and priority management, and problem-solving skills.

Keith_Richards [23]

Answer:

-3.91%.

Explanation:

The Duration Adjustment (% change in bond price) is given by:

= (Duration) * (Change in yield in %)

= -(7.81) x (0.5%)

= -3.91%

The Convexity Adjustment is given by:

= 0.5 * Convexity *  (Change in yield, as a fraction)^2

= 0.5 * 99.87 * (0.005)^2

= 0.5 * 99.87 * 0.000025

= 0.001248375

= 0.0012%

Thus, the convexity correction is 0.0012%

Thus, the total change in bond price = -3.91% + 0.0012% = -3.91%.

Ratling [72]

Answer:

Explanation:

:

Sharon and Amy are roommates. They spend most of their time studying (of course), but they leave some time for their favorite activities: making pizza and brewing root beer. Sharon takes 4 hours to brew a gallon of root beer and 2 hours to make a pizza. Amy takes 6 hours to brew a gallon of root beer and 4 hours to make a pizza.  

a. What is each roommate’s opportunity cost of making a pizza?

Each room mates opportunity cost of making pizza is the beer they would have made with the time spent on making pizza which is

Sharon = 2/4 gallon of beer or 0.5 gallon of beer

Amy = 4/6 gallon of beer or 0.67 gallon of beer

Who has the absolute advantage in making pizza?  

Sharon arguably has absolute advantage because she has comparative advantage in producing both items because she spends less time producing both however she spends half the time of Amy in producing Pizza in particular

Who has the comparative advantage in making pizza?  

Sharon because she spends half the time of Amy in producing Pizza  

b. If Sharon and Amy trade foods with each other, who will trade away pizza in exchange for root beer? Amy will trade pizza for root beer because she has a greater disadvantage in Pizza production in relation to root beer when compared to Sharon. She spends double the time of Sharon in making Pizza but less than double the time of Sharon in making root beer

c. The price of pizza can be expressed in terms of gallons of root beer.  

Sharon = 2 hours/4 hours gallon of beer or 0.5 gallon of beer per pizza

Amy = 4 hours/6 hours gallon of beer or 0.67 gallon of beer per pizza

What is the highest price at which pizza can be traded that would make both roommates better off?  

That price should be lower than Amy's cost but higher than Sharon's cost, so they can both make profits. = (0.5+0.67)/2 = 0.585 gallon of root beer

What is the lowest price? Explain.

The lowest price will be the opportunity cost of Sharon which is 0.5 gallon of root beer because if the price is lower it becomes a loss to Sharon
