Question

Do you think that the 330 triathletes who responded to the survey may be considered a random sample from the population of triathletes?

Answer 1

Depending on how many could have taken the survey, it would be a random sample of the population of triathletes. However, if these surveys were conducted at a single event that was in an area where only a small range or area of triathletes attended, it may not be a good random sample.
