Final answer:

Increasing the sample size from 10% to 15% would result in the sample mean less closely reflecting the population mean.


Explanation:

The sample mean would less closely model the population mean if the company were to randomly sample 15% of the employees instead of 10%. Increasing the sample size beyond the original 10% would lead to a greater deviation from the population mean, impacting the accuracy of the sample representing the entire employee population.
