You want to create a binary variable Salary$\_$Cat in the data frame df$\_$Hi$,$ assigning $1$ if

the player's salary is above the median salary and $0$ otherwise. Which of the

following lines of code will do that?

df$\_$Hi$[\text{'}$Salary$\_$Cat'$]=$ df$\_$Hi$[\text{'}$Salary$\text{'}].$apply$($lambda x: $1$ if $x>$ df$\_$Hi$[\text{'}$Salary$\text{'}].$mean$()$

else $0)$

df$\_$Hi$[\text{'}$Salary$\text{'}].$apply$($lambda x: $1$ if $x>$ df$\_$Hi$[\text{'}$Salary$\text{'}].$median$()$ else $0){?}^2$

None of the choices works!

df$\_$Hi$[\text{'}$Salary$\_$Cat'$]=$ df$\_$Hi$[\text{'}$Salary$\text{'}].$apply$($lambda x: $1$ if x $>$

df$\_$Hi$[\text{'}$Salary$\text{'}].$median$()$ else $0)$
