The percent difference between 35% and 83%.

Here's the deal: (stats question, not my question) In 1965 35% of those polled thought cohabitation was NOT a sin. In 2000 83% of those polled thought cohabitation was NOT a sin. So. Sum up? What is the significance beyond 'more people today are tolerant of cohabitation'---?????

Is there really that little surface area on the earth? Are we talking land only or land and water?

Maybe they polled more people who were actually cohabitating in 2000 because those who believed in cohabitation in 1965 might have kept it hidden whereas now it's not taboo. Those who do cohabitate would be more tolerant of it. Not trying to be facetious, it just sounds that way.

Chick, I TOTALLY tried that tact. I was told that this is a PURE stats course and NOT a course on Research Methods. We are supposed to pretend that the sample is legit.

Oh, then I don't know.

:p

Are they asking for the percent increase? If so, you're looking at:

83-35 = 48
48/35 = 1.37, or a 137% increase in the number of people who found cohabitation to be acceptable.

Seems like there is more surface than that.

I assume they are talking dry land but I didn't measure it. #41

35% of the 1965 population to 83% of the 2000 population would be more than 137%, wouldn't it?

Trilby · 01-31-2007, 08:05 AM

Thanks, Clobfobble! totally the right answer!

Nah, because remember a "100% increase" would be doubling your number, and then this is just a little more than that..

Surface area of a sphere: 4 * pi * r * r

r = 3978

3978 * 3978 * 3.1416 * 4 = SA of Earth

198,856,795 approx surface area of Earth.

r = radius = diameter / 2

c = circumference = 25,000 miles

circumference of Earth approx 25,000 miles

radius of Earth approx 3978 miles

c / d = pi

25000 / d = 3.1416

25000 = 3.1416 * d

25000 / 3.1416 = d

7958 miles = d

d = 2r

7958 = 2r

7958 / 2 = r

3978 = r

Thus, for any circle, if you divide the circumference by the diameter, you get a value close to Pi. This relationship is expressed in the following formula:

C over d equals Pi

Well, BigV, the good news is that Earth isn't as superficial as I thought.

hehe.... I have to keep my algebra muscles limber for middle school math homework. That's why I tried to show my work. I treated it like a homework problem SonofV might have. You see the first draft, not the polished final product. But that's where the work is, the rest is finish carpentry, something neither of us is passionate about. I leave that to artisans like Griff and Happy Monkey.
