    YouTube T2-11 Test of sample variance

    If (we can assume) the population is normal, then the chi-square distribution can be used to test the sample variance (this is analogous to using the student's t for a test of the sample mean). David's XLS: http://trtl.bz/011018-yt-sample-variance-xls

    FAQ Exam How do we get critical (lookup) values during exam; e.g., critical normal Z or critical student's t?

    Are lookup tables provided in the FRM exam or do we use the calculator to find the critical values of the normal or t distributions? Thanks.
