A Gallup Poll taken in May 2000 asked the question: “In general, do you feel that the laws covering the sale of firearms should be made more strict, less strict, or kept as they are now?” Of the 492 men who responded, 52% said more strict, while 72% of the 538 women who responded said more strict. Assuming these respondents constitute random samples of US men and women, estimate the difference in the proportions of women and men in the population who think these laws should be made more strict with a 98% confidence interval.

What subject is this?

Step-by-step explanation:

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
