It includes variables regarding their age, gender, major, GPA, Bachelors GPA, course load, English speaking status, family, and weekly hours spent studying.

1.It is pretty common across most schools to find the grades at the MBA level divided between A’s and B’s. As such, you expect the mean GPA to be around 3.50. Using the sample of 200 MBA students, conduct a one-sample hypothesis test to determine if the mean GPA is different from 3.50. Use a .05 significance level.

2.Assume you read in the website that the average age of their MBA students is 45. Is this really true or have they failed to update this correctly? You think it is far less because there have been a lot more students going straight from their Bachelors to their Masters since the economy is so bad. You took a sample of 200 students (in the data file). Conduct a one-sample hypothesis test to determine if the mean age is less than 45. Use a .05 significance level.

3.You have heard from idle chatter that most students don’t declare a major in their MBA programs. You took a sample of 200 students (in the data file). Conduct a one-sample hypothesis test to determine if the proportion without a major is greater than 50%. Use a .05 significance level.The requirements please describe how you got your answer. Use apa format and below will be the podcast and also what is needed to answer questions and please cite source and three or more sources are needed.Mist be scholarly sources.A quick review of how to complete the course. Watch the Attend. Read the Chapter. Go to Dr. M’s website (http://www.drjimmirabella.com/Bethel/) download the “Excel Data File – Student Data” because you will use this a lot (download it from Dr. M’s website). Work the sample problem for the Unit. Then work the assigned Complete problem. You will be copying and pasting columns of data for the Complete assignments into the Excel spreadsheets provided by Dr. M. Look for the yellow highlighted cells – these are the ones where you will be entering information.DEFINE WHAT YOU ARE DOING. This is NOT a step by step description of your actions. This is where you define and explain the statistics you are going to run to answer the question. For example, What is a categorical analysis? Why run it? What will it tell you? What variables are you going to use to run it? Show me that you know what you are running.Here’s the biggest difference: when you do the Complete assignments the coding for gender is 0=MALE, 1=FEMALE. Always use this coding. The data file on Dr. M’s site uses this coding
