In a past presidential election, the actual voter turnout was 60%.
In a survey, 1070 subjects were asked if they voted in the presidential election.
Find the mean and standard deviation for the numbers of actual voters in groups of 1070.
(Round answer to one decimal place.)
(Round answer to two decimal places.)
Give the interval of usual values for the number of voters in groups of 1070.
(Enter answer as an interval using square-brackets only with whole numbers.)

In the survey of 1070 people, 715 said that they voted in the last presidential election. Is this result consistent with the actual voter turnout, or is this result unlikely to occur with an actual voter turnout of 60%?
