It is appropriate to use the pooled estimate of the common population proportion when the null hypothesis of equal population proportions is accepted. This occurs when the sample proportions are found to be not significantly different from each other, and the pooled estimate is used as the best estimate of the common population proportion. Therefore, choice C is the correct option as it indicates the situation where the null hypothesis is accepted and the pooled estimate is appropriate to use.
