The 99% confidence interval for the difference between the average years of service between men and women would be = 3.43.

<h3>What is confidence intervals?</h3>

Confidence interval is defined as the statistical parameter that is used to know if a set of values would fall within a certain range of population or not.

Using the statistical table, the value of 99% or 0.99 confidence interval has a z-score = 2.576

The standard error that exists between the bothe value = SD/Ö

Where SD = difference between the standard deviations = 8.39 - 4.39 = 4

Where ñ = different between the average years of service = 9.62

Standard error= 4/√9.62 = 4/3.01 = 1.33

The confidence interval = 2.576 × 1.33 = 3.43.
