1. Bay Area University enrolls MBA students in three cohort programs: Weeknight, Saturday, and Distance. Dean Ed Epstein wants to know if there is a difference in the average of the students in the three programs. He has his assistant take a random sample of 5 students from each program and record their ages.
Weeknight Saturday Distance
29 32 25
27 33 24
30 31 24
27 34 25
28 30 26
a) State the Null hypothesis and the Research hypothesis to be tested
b) Calculate the F statistic.
c) Should the Null hypothesis be rejected at the 5% level of significance?
d) Draw box plots for the different programs.
e) Using the least-significant difference test, identify the significant differences between the programs.

This solution gives the step by step method for computing ANOVA test statistic for MBA cohort program data.
Research using statistical tests
Select an article that describes research using one or more statistical tests (z, t, ANOVA, chi square, regression) as part of the data analysis. Describe the study using the following information:
1) State the research problem and purpose. Why was the study needed and what did the author want to accomplish?
2) Identify the stated or implied research question and sub-questions.
3) Describe the implied or stated assumptions and limitations. How did each affect the study?
4) Define the population and sampling methods, variables, and data collection method(s).
5) Identify the data analysis methods. Which statistical tests were used?
6) State the findings. Did they answer the research questions? Were the findings statistically significant? Is the information useful in improving management (or other) practice?
7) Discuss whether the findings justified the conclusions and or recommendations.View Full Posting Details
