In case 4, population 1 has a larger standard deviation than population 2, indicating greater variability in the data. As a result, a larger sample size is required from population 1 in order to achieve the same level of precision as the sample size from population 2. Therefore, the required sample size from population 1 is smaller than the required sample size from population 2.
