For a small sample difference of means test where n1 = 9 and n2 = 11, and we can assume the population variances are equal, the degrees of freedom for the test statistic is: Group of answer choices 18 20 19 10
Added by Chad I.
Step 1
We need to find the degrees of freedom for a t-test comparing the means of two small samples, assuming equal population variances. The sample sizes are n1 = 9 and n2 = 11. Show more…
