A study reports the results of an independent samples t test (between two samples: Sample X and Sample Y). The results are t(12) = 2.245, p<.05, d = 1.11. Sample X had 6 participants. How many participants did sample 2 consist of?

What is the t-cut-off value for a study in which we test a non-directional hypothesis, with 14 participants in a within-groups design (i.e., a paired samples t test is used) at an alpha level of 0.1

We are conducting a single-sample t test, based on the following sample: [6, 8, 10, 11, 14]. Calculate the estimated standard error of the comparison distribution.
