Statistics One Sample Hypothesis Test Essay

 

Questions:

Please provide your work in detail and include in-text citations. Justify use of the statistic in answering the above questions. At least five (5) peer-reviewed sources are required.

In an article in the Journal of Retailing, Kumar, Kerwin, and Pereira noted factors affecting merger and acquisition activity in retailing. As part of the study, the authors compared the characteristics of “target firms” (firms targeted for acquisition) and “bidder firms” (firms attempting to make acquisitions). Among the variables studied in the comparison were earnings per share, debt-to-equity ratio, growth rate of sales, market share, and extent of diversification. 

1)Let ? be the mean growth rate of sales for all target firms (firms that have been targeted for acquisition in the last five years and that have not bid on other firms), and assume growth rates are approximately normally distributed. Furthermore, suppose a random sample of 25 target firms yields a sample mean sales growth rate of 0.16 with a standard deviation of 0.12. Use critical values and this sample information to test H0: ? = .10 versus Ha: ? >.10 by setting ? equal to .10, .05, .01, and .001. How much evidence is there that the mean growth rate of sales for target firms exceeds .10 (that is, exceeds 10 percent)? 

2)Now let ? be the mean growth rate of sales for all firms that are bidders (firms that have bid to acquire at least one other firm in the last five years), and again assume growth rates are approximately normally distributed. Furthermore, suppose a random sample of 25 bidders yields a sample mean sales growth rate of 0.12 with a standard deviation of 0.09. Use critical values and this sample information to test H0: ? = .10 versus Ha: ? > .10 by setting ? equal to .10, .05, .01, and .001. How much evidence is there that the mean growth rate of sales for bidders exceeds .10 (that is, exceeds 10 percent)?

Walden University Importance of Relationships in GSS Dataset Discussion

 

For this Discussion, you will explore the relationship between these components and understand the trade-off between reducing risk in our confidence of estimates and increasing precision.

To prepare for this Discussion:

  • Review Chapters 6 and 7 of the Frankfort-Nachmias &      Leon-Guerrero text and in Chapter 7, p. 188, consider Hispanic migration      and earnings and focus on how different levels of confidence and sample      size work together.
  • Review Magnusson’s web blog found in the Learning      Resources to further your visualization and understanding of confidence      intervals.
  • Use the Course Guide and Assignment Help found in this      week’s Learning Resources to search for a quantitative article related to      confidence intervals.
  • Using the SPSS software, General Social Survey dataset      and choose a quantitative variable that interests you.

Using SPSS:

  1. Take a random sample of 100.
  2. Calculate the 95% confidence interval for the variable.
  3. Calculate a 90% confidence interval.
  4. Take another random sample of 400.
  5. Calculate the 95% confidence interval for the variable.
  6. Calculate a 90% confidence interval.

Post your results, the mean of Age to verify the dataset you used, and an explanation of how different levels of confidence and sample size affect the width of the confidence interval. Next, consider the statement, “Confidence intervals are underutilized” and explain what the implications might be of using or not using confidence intervals. Provide examples based on the results of your data. Also, use your research to support your findings.
