Answer #1

YHAT= - 0.32167 + 0.049532 X1

This estimated regression equation signifies the following.

(a) The intercept value is -0.32167, which means that if the value of X1 (independent variable) is 0, estimated value of YHAT (dependent variable) is -0.32167.

(b) Value of slope coefficient is 0.049532, which means that if X1 (independent variable) increases (decreases) by 1 unit, value of YHAT (dependent variable) will increase (decrease) by 0.049532 unit.

(c) Since no other value (R2, p-value or t-statistic) are provided, we cannot comment on goodness of fit or statistical significance.
