Let p₁= population proportion for population 1, p₂= population proportion for population 2, ... and p_k= population proportion for population k.Consider the following null hypothesis: H₀: p₁= p₂= ... = p_k. Which of the following statements is correct?

a. The alternative hypothesis to the null hypothesis stated above must be: H1: Not all population proportions are equal.

b. If the sample data and the chi-square test computations indicate H₀cannot be rejected, we cannot detect a difference among thekpopulation proportions.

c. If the sample data and the chi-square test computations indicate H₀can be rejected, we have the statistical evidence to conclude that one or more population proportions differ from the other population proportions.

_d. All of the above.
