30 randomly selected cans of Coke are measured for the amount of cola in ounces. The sample values have a mean of 12.18 ounces and a standard deviation of 0.118 ounces. Test the claim that cans of coke have a mean amount of cola greater than 12 ounces.
What is the pvalue?
A) 8.532
B) 1.000
C) 0.9999
D) ≤ 0.0001

Z = (scoremean)/SEm
SEm = SD/√n
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to your Z score.
