A phone survey conducted in the city of Long Beach, CA, reported that a greater proportion of nonsmokers endorsed a ban on smoking in alcohol-serving establishments than did smokers. What type of study design was this?

cross sectional study design                            

Explanation:

The cross-sectional analysis in scientific investigation, sociology, and biological instance is a form of experimental study that analyses information from a community, or a particular portion, at a particular time stage— which is, cross-sectional results.

The use of regularly gathered data makes it possible to conduct broad cross-sectional analyses at very little cost. Natural improvement has been proposed from inexpensive cross-sectional analyses with regularly gathered data indicating hypotheses, to situation-control experiments examining them more precisely, then to longitudinal trials and research costing considerably further and taking far longer, but which can offer better proof.
