Question

According to USA Today ( 20 April 1998, Snap­shot), a poll of 8709 adults taken in 1976 found that 9% believed in reincarnation, whereas a poll of 1000 adults taken in 1997 found that 25% held that belief.
a. Assuming a proper random sample was used, verify that the sample proportion for the poll taken in 1976 almost certainly represents the population pro portion to within about 1%.
b. Based on these results, would you conclude that the proportion of all adults who believe in reincarnation was higher in 1997 than it was in 1976? Explain.
