	Coefficient
intercept	950.1896
Rank	-0.6678
StdNum	0.001978

remu = B0+B1rank+B2Stdnum+u

A.)wht is most likely sign for B2, explain why.

B.)Estimate equation with or without stdnum.report the resul in equation.explain the relation between dependent and independent variables,are they statistically significant?

Expert Solution

It is a Multiple Regression equation

Remu is a dependent variable and other two variables such as Rank and Stdnum are considered as independent variables.

The Equation is

A. Beta 2 is negative. It indicates that Rank has a negative or inverse relationship with Remu. It seems when Remu is increasing the rank will be decreased.

B Estimate equation with stdnum

It can be written using the values as

B Estimate equation without stdnum

It can be written using the values as

The relationship between Dependent and independent variables

Rank has a negative relationship with the dependent variable remu. It indicates that When remu is increased, the rank will be decreased. The relationship is inverse. But the std Num keeps a positive relationship with Remu. It shows that when stdnum is increased the remu will also be increased. Both the independent variables influences the dependent variable significantly. The percentage of significance can be explained by the t statistics.
