1. The problem statement, all variables and given/known data
For a quantitative variable, you want to test H0; $$\mu$$=0, against Ha, mu not equal 0. The 10 observations are 3,7,3,3,0,8,1,12,5,8

a. I get this part
b. The P-value is 0.002. Interpret, and make a decision using a significance level of 0.05. Interpret.
c. If you had used Ha: mu>0, what would the P-value be? Intrepret.
d. If you had instead used Ha: mu<0, what wold the P-value be? Intrepret it.

2. Relevant equations
b.
Does intrepret mean draw it, or say it? I have the table, but the value don't go as low as 0.002. What do I do?

c&d. I'll probably understand this if I can understant part b.
