ratio of variances for two samples
-a.b.c.d.
difference of two sample means
-a.b.c.d.
variance compared to a predicted population variance
-a.b.c.d.
mean compared to predicted sample mean with known population variance
Explanation / Answer
ratio of variances for two samples
it is f test, we compare the varaince between two population data
difference of two sample means
t-test
variance compared to a predicted population variance
it is 2-test, we use 2 to predict population variance or standard deviation
data using sample variance or sd
mean compared to predicted sample mean with known population variance
it is z-test, when population variance is known, we use z test to predict
mean data and where in we use t test whe variance is unknown
