CHAPTER ONE INTRODUCTION 1.1. Introduction Have you ever stopped to think about where your electricity comes from? Nowadays, it is no longer only a question of ‘how much electricity do I want to use? However, this type of question which is ‘what kind of electricity do I want to use?’ is also count.

Correlation Name: Institution: Correlation The main purpose of linear correlation is to show how strongly two variables affect each other. If the increase in one variable leads to no definite change in the other variable, we say that there is no correlation between the two variables. If the increase in one leads to the increase in the other, we say there is a positive correlation. However if the increase in one leads to a decrease in the other, there is negative correlation. The strength

Ch 13 Ch 13. (37). It's so close to 1 that it really doesn't need testing, but just for drill: H0: rho <= 0 Ha: rho >0 Critical value for t (0.05, 1 tail, n-2=25-2=23 degrees of freedom) = 1.714 Test statistic: t = r/sqrt((1-r^2)/(n-2)) t = 0.94/sqrt((1-.094^2)/(n-2)) t = 0.94/sqrt(0.1164/23) t = 13.21 Since the test statistic exceeds the critical value, we can reject the null hypothesis in favor of the alternative and presume that there is a positive correlation between
