There are 3,000 people at a concert. You survey a random sample of 200 people and find that for 35 of them this is the first concert they have ever attended. Estimate how many people are attending their first concert that night.

The reason there are so many names is because we are in a study group. We are sorry there is only one computer and we all had different question. Please help MY name is Gwen

35 is 17.5% of 200
So, 17.5% of 3000 = 525 as you calculated.
good work.
