My hypothesis is "Is the average rainfall in June in countries of the Northern different from that of countries in the Hemisphere The Southern Hemisphere?"

I want to know how to use difference in mean significant test (T-test) to prove this hypothesis

The mean of country in the Southern Hemisphere is 77. 26666667

The mean of country in the Northern Hemisphere is 77. 94

Can you please write down the discussion and conclusion for this?

Thank you!
