... The hypothesis test of the difference of three or more population means has four assumptions. 1. The k samples are each obtained using simple random sampling. 2. The k samples data independent of each other within and among the samples. 3. The k populations are normally distributed. 4. The k populat ...

Confidence Intervals and Tests of Significance
... The first confidence interval for µ1 − µ2 is the two-sample t procedure. If we can assume that the two samples have a common standard deviation, then we pool the data to compute sp , the pooled standard deviation. Matched pair procedures use a one sample procedure on the difference in the observed v ...
