An important part of evaluating strategies is determining the nature and extent of changes in an organization’s external opportunities and threats as well as internal strengths and weaknesses. Changes in these underlying key factors can indicate a need to change or modify the firm’s strategies. Instructions As a class, discuss positive and negative changes in your university’s external and internal factors during your college career. Begin by listing on the board new or emerging opportunities and threats. Then identify strengths and weaknesses that have changed significantly during your college career. In light of the external and internal changes that were identified, discuss whether your university’s strategies need modifying. Are there any new strategies that you would recommend? Make a list to recommend to your department chair, dean, president, or chancellor.

Sabrina, Kris, and Kelly are the only three residents of the small town of Charleston. They are considering whether to hire a police officer to patrol the town. Sabrina values the police officer at $610 per week, Kris values the police officer at $230 per week, and Kelly values the police officer at $150 per week. The competitive wage for a police officer is $900 per week.

a. If the protection provided by the police officer to one resident does not diminish the protection provided to the other residents, then the police officer is (Click to select) a commons an excludable a rival a nonrival a nonexcludable good.

b. Suppose Sabrina proposes a tax whereby all three residents split the cost of the police officer equally.

Will the majority of them support this tax?

  • No, they will not support the tax.

  • Yes, they will support the tax.

Is this outcome socially efficient?

  • This outcome is not socially efficent.

  • This outcome is socially efficient.

c. Suppose Kris suggests a proportional tax on income to pay for the police officer. If Sabrina earns $4,000 per week, Kris earns $1,500 per week, and Kelly earns $500 per week, what proportional tax on income would just cover the cost of the police officer?

Instructions: Enter your response as a percent.

A proportional tax rate: %

Will the majority of them support the tax?

  • Yes, all three would support the tax.

  • No, all three would not support the tax.

  • No, two of them would not support the tax.

  • Yes, two of them would support the tax.

d. Is a regressive tax system likely to lead to the socially optimal outcome in this case?

  • No

  • Yes

Cholesterol Levels A family physician wanted to know if age and gender were factors that explained levels of serum cholesterol (in mg/dL) in her adult patients. She randomly selects two patients for each category of data and obtains the following results:

Serum cholesterols are known to be approximately normally distributed and the population variances are equal.

(a) What type of factorial design is this? How many replications are there within each cell?

(b) What is the response variable? What are the two factors?

(c) Determine if there is significant interaction between age and gender.

(d) If there is no significant interaction, determine whether there is significant difference in the means for the three age groups. If there is no significant interaction, determine whether there is significant difference in the means for the genders.

(e) Draw an interaction plot of the data to support the results of parts (c) and (d).

(f) The residuals are normally distributed. Verify this.

(g) If there is significant difference in the means for the three age groups, use Tukey’s test to determine which pairwise means differ using a familywise error rate of . If there is significant difference in the means for gender, use Tukey’s test to determine which pairwise means differ using a familywise error rate of

Open the MDS data-set

a. Using the ALSCAL program, assume that the data are metric (interval) and compute the distance matrix between pairs of sports for the 50 respondents with two-dimensional MDS

b. Which sports are the most similar according to consumer perceptions?
Which ones are the most different?

c. Save the final co-ordinates and compute the bivariate correlations with the expert panel evaluations

d. Try the three-dimensional configuration. Which solution works betteraccording to the STRESS value and R2?

e. Repeat the analysis, this time looking for similarities between respondents for the ten sports on two-dimensions

f. How many clusters of consumers appear from the graph?

g. Run a principal component analysis on the 50 consumers (hint – transpose the data-set), extract the first two components and run a cluster analysis. Do results look similar to the ones of MDS?

h. Save the final co-ordinates and compute the bivariate correlations with the expert panel evaluations
