Calculate the mean of the values in x$\_$train and y$\_$train, storing the resulting values in variables named mean$\_$x and

mean$\_$y$.$ You may use the sum$()$ function, as well as the variable n$\_$train that you defined earlier in the notebook.

Print the results with text output as shown below. Round the displayed value of mean$\_$x to $2$ decimal places, and round

the displayed value of mean$\_$y to $4$ decimal places. Do not round the actual values stored within the variables

themselves, just the values displayed.

Mean of X $=$ xxxx

Mean of Y $=$ xxxx
