If cov(x,y)= 7.5075 and 
,then the sample slope coefficient is 2.145.
Cov(X,Y)
The covariance between two variables X and Y, measuring how changes in one variable are associated with changes in the other.
Sample Slope Coefficient

Final Answer :
True
Explanation :
The sample slope coefficient is estimated as b = cov(x, y)/var(x). Substituting the given values, we get b = 7.5075/ = 2.145. Therefore, the statement is true.
= 2.145. Therefore, the statement is true.
