Explanation / Answer
Sol)
The Regression mdoel is
y=8.4610 + 0.0210 (X1) - -0.3061(X2) + 0.0204(X3) + 0.0165(X4) - 0.1238 (X5) +0.0132 (X6) +0.000 (X7) -0.0102 (X8)
From above model there is Positive correlation between Y and rooms, radial, proptax,lowstat
And Negetive correlation between Y and dist, stratio,crime.
