In a test of Upper H 0: mu=100 against Upper H Subscript a: mu not equals100, the sample data yielded the test statistic z=2.24. Find the Upper P-value for the test.
Solution:
Given that,
This is two tailed test.
P ( Z > 2.24 )
Using standard normal table
1- P ( Z < 2.24) = 1-0.9875 =0.0125
P value = 0.0125
