Answer: C. No, because the size of at least one of the samples is greater than 10 percent of the population

Step-by-step explanation:

To perform an inference with a confidence interval on a mean, certain conditions need to be met for the calculations to to be accurate.

This question concerns the Independence of the sample. In using this method, the observations should be independent of one another and the size of at least one of the samples should not be greater than 10% of the population.

Both the samples of manager A and manager B are in violation of this as they boast of 35 and 40 employees respectively which is higher than 10% of the 100 employee population.
