Suppose an opinion poll predicted that, if the election were held today, the conservative party would win 68% of the vote. if the pollster attached a 95% confidence level to the interval 68% plus or minus 4%, what would that mean?

The correct answer is:

We can be 95% confident that the true proportion of votes for the Conservative property will fall within 4 points of 68%, or the interval 64% - 72%.

Explanation:

The confidence level (95%) tells us the chance that our interval contains the true proportion.

The margin of error (4%) gives us the interval above and below the mean percentage given.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
