Question

If the decision is to reject the null hypothesis of no difference between two population proportions at the 5% level of significance,what are the alternative hypothesis and rejection region? A)H₁: π₁ ≠ π₂; z > +1.645 and z < −1.645 B)H₁: π₁ ≠ π₂; z > +1.960 and z < −1.960 C)H₁: π₁ > π₂; z < −1.645 D)H₁: π₁ > π₂; z < −1.960

The alternative hypothesis is that the proportions are not equal, which is represented by the symbol "≠". The rejection region for a 5% level of significance is determined by the z-value of ±1.960. Thus, choice B correctly represents the alternative hypothesis and rejection region for rejecting the null hypothesis at a 5% level of significance.
