Question $1$

You conduct a survey of businesses to measure the wages Australian businesses pay to their employees. The survey has $10\%$ non$-$response rate. Fortunately the ATO has a dataset that contains the number of employees of each business in Australia, and this dataset can be linked to each business in your survey. Business wages is highly related to the number of employees in a business, so your manager asks you to determine a method to fill in the missing responses through utilising the ATO$$s dataset.

Select the one option below you would suggest: $*$Mandatory
