Question

In a test of H₀:μ = 100 against H_a:μ ≠ 100, the sample data yielded the test statistic z = 2.30. Find the P-value for the test.

P = _______

Answer 1

Answer #1

Answer 2

Answer #2

Here we have: Hypothesis: Ho; pl = 100 Hajj # 100 Test statistics: z-distribution z= 2.30 P-value = 2p (Z >|2.300) = 0.0214
