In the past presidential election, the actual voter turnout was the 61%. In survey, 1002 subjects were asked if they voted in presidential election.
a) Find out the mean and standard deviation for number of actual voters in groups of 1002.
b) In survey of 1002 people, 701 said that they voted in last presidential election (based upon data from ICR Research Group). Is this result consistent with actual voter turnout, or is this result unlikely to take place with the actual voter turnout of 61%? Why or why not?
c) Based upon these results, does it appear that accurate voting results can be obtained through asking voters how they acted?
