I (unfortunately) only have an elementary knowledge of statistics, and so please excuse me for my following basic question.
I have two independent samples (with sample size of 60 and 765 respectively) and I need to test if the mean of first sample is greater than the mean of second sample by a non-zero given value (the two samples have unequal variance). Since, Matlab is the tool that is used in my workplace, I need to do this in Matlab (I had looked at the "ttest2" function in Matlab, but from the help document,I could not figure out how to use ttest2 to test whether the difference between two sample means is greater than a given non-zero value).
Many thanks in advance.
