Create a presentation, 4-6 slides in length, for a potential employer. Include an introduction slide and at least 2 slides highlighting your skills and experience. Finally, create a summary slide that includes a recording of your voice thanking the employer for their time. Employ best practices for preparing a slide set.

Use at least 3 of the following tools in your slide presentation

The traditional retail model has focused on finding high-margin, high-volume products or services because limited space means reduced space inventory. For example, organizations such as Walmart select the biggest hits from the broadest genres, called the “short head.” The short head means Walmart will only carry a select mix of country, pop, and rock that is calculated to provide the greatest cost/benefit. The business model of Amazon is different. Amazon provides the short head but also provides the “long tail” of more than 100,000 different audio selections. The competition for customers between the Walmart and Amazon marketplace is profoundly changing the face of retail business today.

Using the assigned reading and the Argosy University online library resources, find at least three scholarly articles that address similar current trends related to e-business and how e-business is changing the face of businesses today.

Using your company or a real-world example from your research, respond to the following:

Describe how technology is changing the face of businesses today.
Describe the most critical business processes that utilize information systems in your selected company.
Explain how IT makes the company’s business processes faster, cheaper, more accurate, and customer-savvy than that of competitors.
Cite at least three sources found in your online library research.

Give reasons and examples from your research to support your responses.

Write 3–5-page paper in Word format. Be sure to use and cite the module readings.

Change is everywhere, yet very few people seem to embrace the concept. We are, for the most part, creatures of habit and follow daily routines. When change occurs, our activities and thought patterns are disrupted.

Write a four- to five-page APA formatted paper (excluding the title and reference pages), using a minimum of three scholarly sources in addition to the textbook, analyzing the internal and external factors contributing to an individual’s resistance to change.

Describe a situation where you or someone you know was resistant to change as identified in one of following areas:

Self-interest

Lack of understanding

Lack of trust in management

Differing assessments of the need for change

Low tolerance for change

Explain whether the resistance to change was caused by an internal or external factor. Using Kotter’s theory for change, provide a plan for overcoming that resistance. What will be done and how will you know that the plan has worked?

Project Part B: Hypothesis Testing and Confidence Intervals

Your manager has speculated the following.

a. The average (mean) annual income was greater than $45,000.

b. The true population proportion of customers who live in a suburban area is less than 45%.

c. The average (mean) number of years lived in the current home is greater than 8 years.

d. The average (mean) credit balance for rural customers is less than $3,200.

Using the sample data, perform the hypothesis test for each of the above situations in order to see if there is evidence to support your manager’s belief in each case A–D. In each case, use the Seven Elements of a Test of Hypothesis in Section 6.2 of your text book with α = .05, and explain your conclusion in simple terms. Also, be sure to compute the p-value and interpret.

Follow this up with computing 95% confidence intervals for each of the variables described in A–D, and again interpreting these intervals.

Write a report to your manager about the results, distilling down the results in a way that would be understandable to someone who does not know statistics. Clear explanations and interpretations are critical.

This study investigates whether there are differences in the outcomes of three different treatments for anxiety. The treatment conditions that are compared are treatment with medication, treatment with psychotherapy, and placebo (inactive pills). In addition, we want to see if gender of the client moderates the effects of the treatment. Every participant had been diagnosed with similar types and severity of anxiety disorders when they entered the study. Each participant was randomly assigned only to one of the three treatment conditions. After 12-weeks of treatment (or placebo), all participants completed two questionnaires to measure worry and general emotion. The higher the scores on these measures, the higher the anxiety level of the participant. Directions: The factorial MANOVA will combine what you have learned previously about 1. Post hoc tests when you have more than two groups on an IV (one-way ANOVA), 2. Main effects and interactions (factorial ANOVA), and 3. Working with multivariate analyses of multiple DVs (one-way MANOVA). Using the SPSS data file for Module 6 (located in Topic Materials), answer the following questions: 1. What are the independent variables in this study? What are the dependent variables? 2. Why is a factorial MANOVA appropriate to use for this research design? 3. Did you find any errors that the researcher made when setting up the SPSS data file (don’t forget to check the variable view)? If so, what did you find? How did you correct it? HINT: Yes, there are coding errors for Measures. 4. Perform Initial Data Screening. What did you find regarding missing values, univariate outliers, multivariate outliers, normality? HINT: Revisit instructions from last module’s readings on how to compute Mahalanobis distance and then analyze for multivariate outliers. 5. Perform a factorial MANOVA on the data. Before interpreting the multivariate results of the MANOVA, check outcomes that test other assumptions for this statistic: equality of covariance matrices (see Box’s Test) and sufficient correlation among the DVs (see Bartlett’s Test of Sphericity). Also check the results of the Levene’s Test of Equality of Error Variances to evaluate that assumption for the univariate ANOVAs that are run and show in the Tests of Between-Subjects Effects output. What have you found about whether the data meet these additional assumptions for the MANOVA and follow-up ANOVAs? Explain. HINTS: · Once in the Options box, remember to check box for “Residual SSCP matrix” to get results for the Bartlett’s test. · Also, remember to ask for post hoc tests for Treatment because there are more than two conditions. Profile plots also help with visualizing interactions. 6. What are the outcomes of the multivariate tests (main effects and interaction)? Report either the Pillai’s Trace or Wilks’s Lambda for each result, as well as the associated F-value and its statistical significance. Use the following format for notation to report each result: Pillai’s Trace OR Wilks’ lambda = ____; F(df, df) = ____, p = ____. HINTS: · Use Pillai’s trace if there are problems with heterogeneity of variance-covariance matrices for the DVs. Otherwise, Wilks’ lambda is fine. · Eta squared cannot be calculated from the information provided in the multivariate tests results. 7. Given the results of the multivariate tests, would you now move on to interpret the results of the Tests of Between-Subjects Tests? If yes, what are the results and what do they mean? (Report each of the results using the format of F(df, df) = _____, p = _____ , h2 = _____.) 8. Because one IV has more than two conditions, you would need to do post hoc tests if the overall F-value was statistically significant. If so, what results did you find? 9. If you had a significant interaction effect, what follow-up tests do you need to perform to understand how gender moderates the effects of treatment? What are the results? 10. Citing the results of your statistical analyses, what is the conclusion you can draw (and support) regarding research question that was posed in this research (see problem statement)? HINT: Use the sample results write-up in the textbook to see what you should report and how to say it. Just substitute the correct language and values for the analyses you have done for this problem.
