Final answer:
The difference in proportions between the populations is significant.
Step-by-step explanation:
The correct answer is A) True.
In this question, we are comparing the proportions of two populations using two independent samples. The sample sizes from the two populations are 638 and 294, with success counts of 94 and 71, respectively. To test if the difference in proportions is significant, we can perform a hypothesis test using the z-test.
Based on the provided information, it is likely that the z-test showed a significant difference in proportions between the populations, leading to the conclusion that the difference in proportions is significant.
