Data Analysis and Decision Making.

Please do not waste my time by contacting me if this is not your area of knowledge. You must be knowledgeble in statistics.

 

There are 3 questions but I only need questions 2 & 3 answered and they are in the attached word document. Also attached is the excel grid to use for the solution. I hope you have the right stat tools (spss) to get this done.  

 

I can only accept your first submission as final, so please accurate in your solution.  The earlier, the better. Thanks
