16. no i dont agree. 1 is the only number that can multiply and equal itself. also, 0.1 is not even a whole number

17. it took 19 to 21 hours. one way to show work is by long division. i dont know how to do another way im so sorry

18. because 15000 is the amount in 50 minutes, so just divide 50 minutes of phones by 50 to get one minute of phones

A recent survey based on a random sample of n=470 voters, predicted that independent candidate for the mayoral election will get

I have an expression

$\sigma = \sqrt{p(1-p)/n}$

floating around in my head; let's see if it makes sense.

The variance of binary valued random variable b that comes up 1 with probability p (so has mean p) is

$E( (b-p)^2 ) = (-p)^2(1-p) + (1-p)^2p = p(1-p)$

That's for an individual sample. For the observed average we divide by n, and for the standard deviation we take the square root:

$\sigma = \sqrt{p(1-p)/n}$

Plugging in the numbers,

$\sigma = \sqrt{.24(1-.24)/490} = 0.019 = 1.9\%$

One standard deviation of the average is almost 2% so a 27% outcome was 3/1.9 = 1.6 standard deviations from the mean, corresponding to a two sided probability of a bit bigger than 10% of happening by chance.

So this is borderline suspect; most surveys will include a two sigma margin of error, say plus or minus 4 percent here, and the results were within those bounds.
