Madeline surveyed the first 20 customers who entered a mall about whether they would like to have the mall open earlier. Of the 20 customers surveyed, 15 would like to have the mall open earlier. Which statement BEST explains why the results are invalid? Only one question was asked in the survey.

Only 15 customers said they wanted the mall open earlier.

The customers surveyed live near the mall and shop in the morning.

The customers surveyed are not representative of all the customers who come to the mall.

Step-by-step explanation:

The last statement : "The customers surveyed are not representative of all the customers who come to the mall".

For instance, if only half the mall want the mall to open earlier, but then out of the 20 people that we randomly picked, 15 of them are in the half, we could go to a wrong conclusion that most of the people want the mall to open earlier.

to fix the problem, you might just want to increase the area of the survey next time, or get more people to be in it, etc.

there is no grid

its very big question plz make it small
