A statistical program is recommended.

A study investigated the relationship between audit delay (Delay), the length of time from a company's fiscal year-end to the date of the auditor's report, and variables that describe the client and the auditor. Some of the independent variables that were included in this study follow.

A sample of 40 companies provided the following data.

(a)

Develop the estimated regression equation using all of the independent variables. Use x₁ for Industry, x₂ for Public, x₃ for Quality, and x₄ for Finished. (Round your numerical values to two decimal places.)

ŷ =

(b)

Did the estimated regression equation developed in part (a) provide a good fit? Explain. (Use α = 0.05. For purposes of this exercise, consider an adjusted coefficient of determination value high if it is at least 50%.)

Yes, testing for significance shows that the overall model is significant and all the individual independent variables are significant.No, the low value of the adjusted coefficient of determination does not indicate a good fit.    Yes, the low p-value and high value of the adjusted coefficient of determination indicate a good fit.No, testing for significance shows that all independent variables except Public are not significant.

(c)

Develop a scatter diagram showing Delay as a function of Finished.

A scatter diagram has 40 points. The horizontal axis ranges from 0 to 5 and is labeled: Finished. The vertical axis ranges from 30 to 100 and is labeled: Delay. All the points fall at either 1, 2, 3, or 4 on the horizontal axis, forming 4 columns of points. Moving from left to right, the top point of the first column of points is located at approximately (1, 94). The top points of all subsequent columns extend downward in a diagonal direction. The bottom points of each column follow this same pattern.

All the points fall at either 1, 2, 3, or 4 on the horizontal axis, forming 4 columns of points. Moving from left to right, the top point of the first column of points is located at approximately (1, 92). The top points of the next two columns extend slightly upward in a diagonal direction. The top point of the last column extends downward from the top point of the previous column. Moving from left to right, the bottom point of the first column is located at approximately (1, 54). The bottom point of the next column extends downward. From this point, the bottom two points of the last two columns extend upward in a diagonal direction.

What does this scatter diagram indicate about the relationship between Delay and Finished?

The scatter diagram suggests no relationship between these two variables.The scatter diagram suggests a linear relationship between these two variables.     The scatter diagram suggests a curvilinear relationship between these two variables.

(d)

On the basis of your observations about the relationship between Delay and Finished, use best-subsets regression to develop an alternative estimated regression equation to the one developed in (a) to explain as much of the variability in Delay as possible. Use x₁ for Industry, x₂ for Public, x₃ for Quality, and x₄ for Finished. (Round your numerical values to two decimal places.)

Performing Monohybrid Crosses

A monohybrid cross is addressing the inheritance of one gene. Answer the following questions:

Question 1:

Drosophila melongaster, more commonly known as the fruit fly, can have red or white eyes. You breed a red-eyed fly to a white-eyed fly and get 50 offspring that all have red eyes. Which trait is dominant?

Question 2:

Consider an offspring from the previous question. Its phenotype is red eyes.

What is its genotype? (Circle one of the choices below)

Homozygous dominant, Heterozygous, or Homozygous recessive

Question 3: (2pts)

Next, you perform a cross of two heterozygous, red-eyed flies. They have 100 offspring. How many of these offspring do you predict will have red eyes? Show your work using a Punnett square. [Use letters R and r to designate the alleles]

Question 4:

Suppose you found a fly that had escaped and was flying around your lab. He has red    eyes, but you do not know his genotype. To find out, you cross him with a white eyed fly (since you know her genotype). The result is 50% white eyed and 50% red eyed offspring. What is the escaped fly’s genotype? Explain how you know.

X-linked Inheritance

Consider this imaginary animal, the tree rat. They are usually black, but sometimes they can be purple. The allele for the purple color is X-linked. You manage to capture two of these animals from the same family, a black female and her purple male offspring.

Question 5:

What is the genotype of the black female mother?

Question 6

Do you know the phenotype of the father based on the male offspring? Why or why not?

Question 7: (2pts)

Next you breed the tree rats to each other (inbreeding is acceptable in this case). What percent of the offspring do you expect to be purple? Are any of them female? Use a Punnett square to show your work. [Use the letters B (black) and b (purple) to represent the alleles.]

As you learned in your reading of Chapter 7, when considering expansion into international markets, two of the most important issues a company’s executives face are: (1) which of the three main competitive approaches to take, and (2) which strategic option for entering a foreign market to employ.

GENERAL INSTRUCTIONS:

For the purpose of this Discussion, assume that you are in charge of recommending an international strategy for your U.S.-based company. Your company recently set a strategic objective to expand into each of the following three (3) markets within the next 3 years: Brazil, India, and South Africa.

In each of the scenarios below, you have to make and justify your recommendations to the senior executive team. In each instance, the reasons that support your recommendations must be grounded in relevant concepts covered in TPGS Chapter 7. AND, consideration must also be given to the sociocultural, technological, political, legal, and economic circumstances in each of the targeted markets. [NOTE: You should do adequate Internet research to acquire some understanding of the macro-environment elements in each of these 3 countries.]

SUGGESTION: You may find it easier to comprehend and compare your recommendations (by country) if you organized them in a table or chart format.
