Hello
Is it possible to calculate a 95% confidenceinterval for the slope in connection with a linear regression model?
Regards
Olav
The same question 
I had the same thought. Using the show statistics we have the information we need to construct it by hand, but it would be wonderful if Geogebra could do that. Just as when you show statistics in one-variable analysis it gives a pull down menu with the option of doing a T test /estimate or Z test / estimate of the mean and when you show statistics in multiple variable analysis it gives a pull down menu to do ANOVA or a T test/estimate of the difference of means or paired difference, it would be great if when you show statistics in Two Variable Regression Analysis it gives the option of doing a T test/estimate of the slope. Thanks!
