In February 2012, a bill was introduced into the Ohio State Senate that would outlaw smoking in vehicles if young children are present. That same month a poll was conducted by Quinnipiac University and asked randomly selected Ohio voters if they thought this bill was a good idea or a bad idea. Of the 1,421 respondents, 55% said it was a good idea. We can use this sample proportion to investigate whether more than half of all Ohio voters in February 2012 thought that this bill was a good idea

Is it reasonable to conclude that exactly 55% of Ohio voters agree with the ban on smoking in cars when young children are present? Explain why or why not.
