Use technology to determine the correlation coefficient between the following variables.?
First you work out Sxx, Syy and Sxy. The equations for these are Sxx=(∑x^2)-(((∑x)^2)/2). It's the same for the others, use page 17 of this http://www.edexcel.com/migrationdocuments/GCE%20New%20GCE/N38210A-GCE-Mathematical-Formulae-Statistical-Tables.pdf ∑x^2 means 3.95 squared, plus 4.18 squared and so on.(∑x)^2 means 3.95+4.18+… and then square the answer. Just replace x with Stock A and y with stock B. I don't have time to do i now, but if I get some, I'll try and do it dor you. By the way. The final answer 'r' has to be between -1 and 1, if it's not, you've made a mistake. Good luck.
Is technology making us a dumber society?
I think that technology has dumbed America down. We as a society now rely on technology for everything. Many people don't know how to live one day without using some type of technology. I think that it is horrible because one day the technology won't be there for us and we won't know what to do. I think that technology has eased us of thinking on our own that many of us don't even know how to think for ourselves. Children are loosing their imaginations because they spend all day watching T.V and playing Video Games. I think that it would be so much better if we taught our children how to think on their own. For example, if we taught them to create their own games or make their own music or things of that sort. The thing that baffles me the most is that although America is the most "Powerful" nation in the world, we are not the smartest. That doesn't really make any sense does it? That we will spend more time wasting our minds away on technology than we will trying to feed our brains with books and writing. Now that we have the ability to have the world at our fingertips, perhaps it will keep people from going out to see things for themselves, to go out of their technological shell and learn about the world firsthand. With the internet we have whatever we want, whenever we want it, so it has created such a LAZY society. The teenage generation of today is so lazy that it scares me to think about how the world will be when they are the ones in the buisness world. They can't even think for themselves! No one wants to be anywhere without thier technology sitting in their pocket. Technolgy should not have turned into the crutch for our lives that it has become.
How can we as a country promote alternative energy, use less foreign oil and reduce global warming?
We as a country first need to be more conservative. We can't be so wasteful in our use of energy. Almost all forms of energy have their downsides. Windfarms are a blot on the landscape (many in Europe think they ruin natural beauty), it remains to be seen if Nuclear energy is completely safe, ethanol fuel will produce H20 which is as bad a greenhouse gas as CO2 (if not worse). Solar energy is probably the best, but it is very expensive. Right now, politicians need to urge us to reduce consumption (and politicians can start by reducing their own consumption). Campaigns waste loads of resources...
