A poll found that 59​% of a sample of 1020 teens in a certain large country go online several times a day.​ (Treat this sample as a simple random​ sample.) Complete parts a through e below.   Find the margin of error for this poll if we want 90​% confidence in our estimate of the percent of teens in the country who go online several times a day.   Explain what the margin of error means.   If instead we need to be 95​% confident, will the margin of error be larger or​ smaller? Explain.    Find that margin of error.
