I'm trying to get the answers to form 1.3 (pg. 25) in the Human Resource Management Applications: Cases, Exercises, Incidents, and Skill Builders 7th Edition. I feel that I am not coming up with the correct data. Anything will help.

Percent Turnover per year

Executive (n=127)	12.8	11.5	9.2	8.3
Physician (n=367)	18.1	17.6	17.9	15.6
Other Professionals (n=615)	22.6	22.1	18.3	15.6
Nonprofessional (n=804)	29.0	26.3	27.1	24.3

Average Cost of Turnover per Individual Over the Four-Year Period by Personnel

Executive	Physician	Other Professional	Nonprofessional

Form 1.3 Calculation of benefits of Higher Employee Retention Using a Base of Year One

Nonprofessional
All Categories

I don't understand how this is insufficient data and maybe this is why I don't believe I'm getting the correct information. For example, if in year one for executives, there was a decrease from 12.8 to 11.5 percent (1.3%), wouldn't that mean you take 1.3% X 127 (N) to get the total number of employees that decreased, then take that number and multiply it by the average total turnover cost ($11,837.50) to get the savings for year two?
