Do you think the U.S. must pursue a program to send humans to Mars? An opinion poll indicated that 49% of the 1093 adults surveyed think that we should pursue such a program.
a. Estimate the proportion of all Americans who think that the United States should pursue a program to send humans to Mars. Find a bound on the error of estimation.
b. The poll actually asked several questions. If we wanted to report an error of estimation that would be valid for all of the questions on the poll, what value should we use?
