Question

NEED OF IMMEDIATE HELP

Answer 1

There are no sampling errors, as all numbers add up to 100, however, there is a bias, as the highest number is 52 for movies, and the person who conducted the survey was a movie theater manager to his own customers.

Answer 2

It is biased because there is over 100 answers there on the graph..If he asked 100 workers then there should only be 100 not 150…
