Need help on if the sample given is random or not random.
The first 50 nurses at a nursing convention write their names on slips of paper and place them in a drawing box. After the box is shaken, 20 names are pulled from the box and each person chosen completes a survey about their transportation to the convention.
Thanks...

    However, if the questionnaire were geared to elicit information from only the first arrivals, then the sample would not be random.
