# Thread: How to Calcualte P-Value?

1. ## How to Calcualte P-Value?

How would I calculate the P-Value for this problem?

In a test of H sub 0:meu=100 against H sub a:meu does not equal 100, a sample of size 80 produces z=.8 for the value of the test statistic. What is the P-Value?

Since we are dealing with a two-tailed test, the p-value would be $2\cdot P\!\left(Z>.8\right)=\dots$
