A sample survey of 50 people in Harrisburg, PA indicates that 10 of them know the mayors name in the neighboring city. Out of 5,500 Harrisburg residents, how many would you predict know the name of the mayor of the neighboring city?
I thought 1100.
I did 10/50=x/5500, is this correct?
Thanks for your help
