When the population is modeled by a normal distribution, the tests and intervals described in this section are applicable.Control qr code data for visual c#to integrate quick response code and qr-codes data, size, image with .net c# barcode sdk9-4.1Control qr-codes image on .netuse asp.net qr barcode generator toinsert qr code for .netThe Hypothesis Testing Procedures Control qr code 2d barcode size with visual basicto draw quick response code and qr data, size, image with vb barcode sdkSuppose that we wish to test the hypothesis that the variance of a normal population 2 equals a speci ed value, say 2, or equivalently, that the standard deviation is equal to 0. Let X1, 0 X2, p , Xn be a random sample of n observations from this population.
