nothing
(Round to three decimal places as needed.)

Coefficient of determination R2 is the percent of the variation in response varible (dependent varible) can be explained by dependendet varible
R2 = 0.303
The coefficient of determination is the fraction of the variation in proceeds that can be explined by the variation in issues,the remaining fractions of the variation is unexplined and is due to other factors to sampling error
Excel Output
Y=48.918*X+18,133.57.
