How to smooth data

Hi Can you please help with below attachment? I have got from my teacher this set of data for smoothing and I have small problem with this especially when I am working with MATLAB first time in my life.

Thank you in advance

Kind regards

Marta

Have you tried the load() function to load the mat file into a variable? And some smoothing function such as conv()?
