Find the percent of seventh graders in the sample that have watched a horse race.
No, because 610, or 60 %, is much larger than 20 %.
Practice makes perfect
We are given that twenty percent of all seventh graders have watched a horse race. In our sample of 10 seventh graders, 6 have watched a horse race. Let's find the percent of seventh graders in our sample that have watched a horse race.
6/10 = 0.6 = 60 %
The value 60 % is much larger than 20 %, so we can say that our sample does not closely estimate the percent of seventh graders that have watched a horse race.
