Correlation and Regression

Dear Remi

here's the results shown in the session window of minitab.

I examined only two parameters: viscosity of the compound and scrap %, where scrap is the Y and viscosity is the X . I got this two variables on 62 samples.

Thanks for your comments.

Correlations: viscosity ; scrap

Pearson correlation of viscosity  and scrap = 0.367

P-Value = 0.005

scrap = - 0.949 + 0.0164 viscosity
