Linear Regression t test and Confidence Interval

Corrected Version for iPad Viewers at http://www.youtube.com/watch?v=vWgKDhki5Sw&feature=share&list=PLC8478000586FA6F9 I introduce the Linear Regression t test and confidence intervals for the slope of a regression line. On the third screen I miscopied the denominator in the formula of Standard Error about the Least-Squares Line. The denominator should be n-2 and not n. I have an annotation correction, but you will not see it without Flash like on an iPad.
