I’m trying to determine whether there is a relationship between e-commerce activities and satisfaction.

1-Using summary output generated in ms-excel regression analysis, make the relevant interpretation using r and r2    (I’ve found the “correlation” coefficient 0,28275. Where does this information belong in regression equation?)

2- Explanation the meaning of regression coefficients

3- is this regression significant? Why?

4- what would you predict satisfaction to be where the e-commerce activities rating is 2.00?
