Suppose you are testing a Null Hypothesis about the population mean, Ho : μ =μ0 against H1 : μ > μ0, with population variance given. The computed value of the test statistic is Zc. What is the p-value for this test, where Φ () is the cumlative distribution function for the standard normal distribution?
1
Φ (Zc)
2
Φ (Zc/2)
3
1 - Φ (Zc)
4
1 - Φ (Zc/2)
