A test of significance is conducted for the hypotheses H 0 : μ = 1000 vs. H a : μ ≠ 1000. Suppose the z −score for this test was calculated as z =-1.26. What is the P-value for this test of significance?
Homework Answers
solution
this is two tailed test
z=-1.26
P(z < -1.26 ) = 0.1038*2=0.2076
P-value = 0.2076 ( using z table )
