I see you have 3 questions here using the same raw data.
You are looking for the correlation, strength of the relationship and a hypothesis test.
How far have you gotten in any of these calculations?

Yeah statistics is not for the feint of heart.
For the hypothesis test you would need the average of each group and then use a t-test to see if there is a significant (alpha=.05) difference in the means.
For the second you would need the correlation coefficient between GWA and DA.
And the third (this question) wants you to test the significance of the correlation coefficient.
Some of the steps/calculations can be done with software (e.g. EXCEL).
If I were to do the calculations and answer the questions here with some detail might take 30-60 minutes just for that.
I teach statistics and it would require an actual lesson (or two) to explain (teach) to you how to do each of these. Not sure if that's what you are looking for. Let me know.
