Order Description
This is Regression Excel work there is two part
you need to know how to find Estimated Coefficient, Standard error, R-squared and explain few question with short answer.
and also second part is about Dummy variable.
I’ll attached the Excel with instruction and some class assignment maybe that can be helpful or not.
I asked about pages to customer service because this is excel work and they told me that I need to estimate the short answer word and count pages and I think it should be around 500 word or low but just in case I put 3pages.
