Thank you very much for taking the time to read this!

I have many (~70) time series showing the average body size (kg) for the ~50 years. Each time series is for the same species but from a different region/area.

I would like to look at the change in body size over time and how this correlates with different regions and variables (e.g., temperature).

I am in over my head! I have scoured through Google and forums but have not found my answer! I would greatly appreciate any help or direction to other resources that you can provide.

Thank you!

Find the probability of obtaining a sample average speed of 66 mph or more if, in fact, the true average speed on that holiday weekend is still 62 mph? μx= σx=
Where do I even start? Im having a hard time understanding what to do? (Using minitab if that is helpful)
