After a mayor announced his plans to cut budget costs in late 2011, the Forum Research polled 1,029 people to measure the mayor's popularity. Everyone polled expressed either approval or disapproval. These are the results their poll produced.- In early 2011, **63 percent** of the population approved of the mayor's actions in office.- In mid-2011, **55 percent** of the population approved of his actions.- In late 2011, the percentage of popular approval was measured at **42 percent**.(a) What is the sample size for this study?
