+501 whon: working Formula X X2 + NA N2 = mean of the samples. S1, S₂ = Stand and deviation of the Samples NA N2 = Sample size Given = 1.02 X2 = 1.42 S = D.07 52 = 0.60 N4 = 24 16 putting the values in the Form wlais N2= 1.02- 1421 0.0.44 24 + 16 -0.4 D. 4 0.0002 + - 0225 0-0227 + = -0.4 0.15 + -2.67 ans
Question 5. (10 points) Use the mean difference and standard error of the difference you calculated in Q3 to find the power of the two- sample t-test to find significance at the .05 level. Was the test adequately powered? Explain why or why not. (see the lecture for equations)
