Work Step by Step

a. The number of people in New York is large. Using sampling would reduce the workload of collecting data. It will also ensure that minimum resources are used to obtain the data. The most appropriate sampling technique to be used here is simple random sampling. This technique will ensure that a representative sample is drawn from the population to be used for analysis. b. Census is an appropriate method because the number of employees is small. The list of all employees and their salaries can be easily obtained to be used to calculate the average.
