The Six basic steps in decision making:

1-Define the Problem

2- Determine the Objective

3- Explore the Alternatives

4- Predict the Consequences

5- Make a Choice

6- Perform Sensitivity Analysis

Write 300 to 400 words on “Determine the Objective.” Describe your own motives and what your short or long term plans are (please explain short term and long term plans separately) after completing your MBA? Knowing you “can’t always get what you want” what can you get? What can you change? Explain how you have to make these decisions under uncertainty. Cite the textbook at least twice applying concepts from the text.

1. The Graduate Management Admission Test (GMAT) is a test required for admission into many masters of business administration (MBA) programs. Suppose a random sample of 8 students took the test, and their scores are given below. 699, 560, 414, 570, 521, 663, 727, 413

-Find a point estimate of the population mean -Construct and interpret a 95% confidence interval for the true mean score for the population.

-How many students should be surveyed to estimate the mean score within 25 points with 90% confidence?

-How many students should be surveyed to estimate the mean score within 25 points with 95% confidence?

-. How many students should be surveyed to estimate the mean score within 25 points with 99% confidence?

As a statistical consultant, you have been asked to develop a linear model which shall be given to first year executive MBA students.

Variable           Name                                                   Description

X1                   Gender                                                Male or Female

X2                   GMAT Score                                      Score on GMAT Test

X3                   College Degree Previously Earned     Bachelors, Masters, or PhD

Y                     Income                                                            Annual Income in Thousand Dollars

Where 1=Male and 2= Female for X1 and B = Bachelors Degree, M=Master’s Degree, and P= PhD for X3.

Question Based on above information.

1. Given this data, recode the variables so that they may be used as potential predictors for Y in a linear regression model.   Redefine your categorical variables and write them out here.

6-13. From a sample of 22 graduate students, the mean number of months of work experience prior to entering an MBA program was 34.86. The national standard deviation is known to be 19 months. What is a 95% confidence interval for the population mean? Compute the confidence interval using the appropriate formula and verify your results using the Excel Confidence Intervals template.

6-15. A survey of 26 college freshmen found that they average 6.85 hours of sleep each night. A 90% confidence interval had a margin of error of 0.497.

      a. What are the lower and upper limits of the confidence interval?
b. What was the standard deviation, assuming that the population standard deviation is known?

On July 1, Midway Distribution Company is considering leasing a building and buying the necessary equipment to operate a public warehouse. Alternatively, the company could use the funds to invest in $148,700 of 6% U.S. Treasury bonds that mature in 16 years. The bonds could be purchased at face value.
