The monthly means for January are the ones where Y==1. You can index Z by that logical vector.

The NorfolkMonMeanTemp.dat seems a matrix with 3 columns.
The questions like extracting the monthly mean for a particular month are matrix indexing.
You can refer the following documentation as a start to understand about retrieving elements from a matrix.
Similarly, refer plot for plotting the mentioned variables.
If you are new to Matlab I strongly suggest doing the MATLAB Onramp course which will help in answering
most of the questions in the attached image.
