Question

125. Consider the following data: Y loos | oos | 0.004 | 0.003 | 0.006 | 006 | 0.009 X 0998 0997 0995 0.996 044 0997 0.9905 0.448 0.4407 0.999 Using Minitab, the regression equation is: | О.01 a· Ya-3.2+4.0 X b. Y-3.2+ 4.45 X c. Y=-4.4+4.0 X d. Y=-4.4+ 454.0 x

Answer 1

using MINITAB the result is as follows :

The regression equation is
Y = - 0.95 + 0.98 X

Either the options are wrong or there is something wrong with printing . The options are bogus . None of them will provide a sensible value for a given X .

Though the r² of the above dataset is very low , close to 1.5% , we should not perform linear regression with this data .
