You are on the staff of a member of Congress who is considering a controversial bill that would provide for government-sponsored insurance to cover care in nursing homes. You report that 1128 letters dealing with the issue have been received, of which 871 oppose the legislation. “I’m surprised that most of my constituents oppose the bill. I thought it would be quite popular,” says the congresswoman. Use a 90% confidence interval to determine if a majority of the voters oppose the bill? How would you interpret this interval to the congresswoman? Are there any problems with this conclusion?
