You work for the Chicago Transit Authority (CTA) which provides over 1.5 million rides on buses and trains every weekday. Your current project is to help the annual planning committee determine where to invest additional resources to make transit easier for more customers. You decide that the best way to gather information about CTA riders is to ask them directly!
You design a survey that will be sent out to all CTA customers in the mail. You are hoping that the responses you receive will make up a random sample of CTA customers. You receive some responses, and are working to identify some trends among CTA customers with the results. You analyze the first 1,000 responses to the CTA survey you mailed out. The responses are shown in the table below.
Select all of the following inferences that can be drawn from the data.
