A survey of 1002 people, 701 said they voted in the last presidential elcetion. Voting records show 61% of the eligible voters voted. Find a 95% confidence interval and see if it corresponds to the 61% statistic. This is what I did.
z/2 = 1.96
p hat = x/n = 701/1002
q hat 1-.6996= .3004
E= 1.96 square root of .6996- .3004 / 1002 = .0284.
That's the right answer but don't know how to type it in my calculator. I keep getting .00124. I have a TI-83 Plus. Could you show me how to type E= 1.96 square root of .6996- .3004 / 1002 in my calculator? Thanks
