T-Test in Hypothesis Testing help!

A brewery claims that the consumers are getting a mean volume equal to 32 ounces of beer in their quart bottles. The Bureau of Weights and Measures randomly selects 36 bottles. Test the claim of the brewery about the mean volume equal to 32 oz. at the .05 significance level.

--What I found: http://upload.wikimedia.org/math/6/0...a3cc6a1131.png: 31.9458333, Σx: 1150.05, Σx^2: 36749.2643, Sx: .5331416883, n= 36

--Now, after this I know i have to write down its original claim and the null hypothesis (*μ = 32) *with its alternate hypothesis. My problem is I don't know to how many digits I'm supposed to round these numbers to. I've already gotten 3 different answers. Can anyone enlighten me? The calc gives me t= -.6093 with the p-value of .5463 (rounded). Should I just put this down? (Nerd)
