... interval for the mean of this data set – Calculate w=t*s/√n – The confidence interval is from m-w to m+w – t* is the value from the t-distribution for which P(t>t* or t<-t*)=1-confidence • e.g. for a 95% confidence interval we want P(t>t* or t<-t*) =0.05 • So P(t>t*)=0.025. From tables or software, ...

... general information about the air movement in an area. However, at rates of less than 5025 fpm it becomes a more important tool in measuring velocity. These instruments are used in one of three ways: 1. Point Method is where the opening is divided into equal sections (such as 9 or 16), and an instru ...
