The amount of solid residues and the concentration of bicarbonate in
mineral water are highly correlated. Use the data set WATERRESID
to set up a straight line regression model for the estimation of the bicarbonate
content from the amount of solid residues in the water. Try to answer the
following questions:
Here are the measurements of the two "unknown" brands of mineral
water ("Fonte Guizza", and "Radkersburger"):
HCO3 Solid
conc. Residues
[mg/l] [mg]

Fonte Guizza 256.2
230
Radkersburger 2111
2850
