Dear Mr. Samuels:

Thank you for your answer. Regarding your questions:

1. Objective: The study will address the needs of training in different sectors.
2. Some variables: size of company, number of employees, dichotomous
variables (yes/no), etc.
3. No, I will not sub-sampling.
4. Sample size in each sector was established previously by another researcher.
