Z-tests, Advanced Statistics

Hello! I am currently in graduate school earning a masters in mental health counseling. I am in a stats course at current and we are reviewing z-scores. I am a little lost because the numbers confuse me. Here is the problem we had for homework:
You have a null hypothesis population of 10,000; µ = 67.6; s= 5.5; one tailed hypothesis where > µ, a = .01. Sample: N = 30; = 72.1, s = 15.6.

I conducted a z-test and got a z score of .82 and a p value of .2061. I now need to know if I should reject or retain the hypothesis and that''s where I''m lost.
