A phone line carrier conducted a survey with their customers to verify their satisfaction with their coverage. Text messages were sent to random customers, asking questions such as: how good the coverage is where they live and they were asked to reply with a number from 1 to 5. The main question was how satisfied with the coverage are the customers and which states have the best and worst results? The population is composed by random customers of the carrier. Some variables to be observed are which plan the customer has, what phone, what area does he/she live (rural, urban). There are 500.000 individuals included in the dataset, divided by state, so 10.000 in each state randomly selected for the research and text messages were sent to different customers until all the numbers for the research were fulfilled.

Question
I need to know first if I can find the sampling variation from this example. Is there enough information to do that?
