The Distance Learning Department is interested in estimating the percentage of college students who primarily use a smartphone to access their online courses in Canvas. In order to collect data to address this issue, Professor Collins surveyed the students enrolled in his online Math 13 courses. The survey posed the question "Which type of device will you primarily use to access your online course in Canvas?". Students had the option to select either a desktop computer, a laptop computer, a smartphone, a tablet, or something else for their response.
