Amanda read a report saying that 49% of teachers in the United States were members of a labor union. She wanted to test whether this was true in her state, so she took a random sample of 300 teachers from her state to test H₀ : p= 0.49 versus Hₐ : P ≠ 0.49, where p is the proportion of teachers in her state who are members of a labor union.
The sample results showed 134 teachers were members of a labor union, and the corresponding test statistic was z ≈ -1.50.
Assming that the necessary condition are met, what is the approximate P-value for Amanda's signficance test?
