The Excel file attached has a dependent variable labeled Y and two independent variables labeled X$1$ and X$2.$

Create a series of indicator variables to categorize the variable X$1$ in the following way. Create a variable named Ind$1$M which takes on the value of one if the variable X$1$ has a value larger than $29$ but less than $70$ and is zero otherwise. Addtionally, create an indicator variable named Ind$1$H which takes on the value of one if the value of X$1$ is $70$ or larger and zero otherwise..$$

If you run a multiple linear regression using Y as your dependent variable and only X$2,$ Ind$1$M and Ind$1$H as your independent variables, then the impact that Ind$1$H has on Y is estimated as $($choose the closest answer$)$
