Explanation / Answer

   When collecting data online, there is a highchance of nonresponse bias. People who are ashamed of theirweight may choose not to reply or to falsify answers givenonline. The data may be a random sample of all data fromonline statistics students, but likely suffers from a type ofresponse bias.    The risks in using this assumption are thatthe data may not be representative of all online statisticsstudents because of bias. Therefore, any calculations madewith this data may be incorrect.
