independent samples with Sx^= Sy = 10.
independent samples with Sx^= Sy = 10.
(a) Calculate Sx – y from formula 14. 2b, assuming nx = ny = 30. (b) Recalculate Sx-y,assuming nx=15 and ny=45.(c)Compare the two values of Sx – y. What principle does this outcome illustrate?
You are given the following scores from two randomly drawn independent samples:
X: 6,7,8,8,11 Y: 3,4,4,7,7
State formally the hypotheses necessary to conduct a non directional test of no difference between the two population means. (b) Complete the test at the .05 abd .01 levels of significance, and state your conclusions.
