Hi Cristina

a.   Design a stratified sample to survey 10% of the employees. (2 marks)

DivisionNumber of employeesNumber Surveyed
Hamilton division25025
Sudbury division23023
Oshawa division11011
Kingston division404

b.   Suggest two other ways to stratify this sample. (2 marks)
Two other ways to stratify this sample is by age and gender, since the older workers could be used to the working conditions whereas the younger workers not so much, or the girls care more about the working conditions and the boys not so much.
