Many movie theaters show advertisements before feature
films to increase concession sales. However, many
customers complain about the length the advertisements
add to their time at the theater. To understand the effect of
advertising, a movie theater manager chooses random
days during the month when the concession
advertisements are not shown. On the remaining days,
the concession advertisements are shown as usual. The
manager then records the concession sales for each day.
What is the explanatory variable in this scenario?
the movie theater patrons
the concession advertisements
* the daily theater attendance
the amount of money collected at the concession
stand
*THE CORRECT ANSWER IS B*
