Researcher suggest that identical twins have many similarities such as body weight even as adults A sample of ten sets of identical twins were weighed and that their weights recorded in kg . The researcher wishes to test whether there is a statistical significance difference in adult weight between 1st and 2 Nd born twin. Given the design of the study and the question of interest which of the following 4 computer output is relevant to use A: paired t test and ci 95% upper bond for mean difference 6.43 T test mean diff=0 (vs <0) t value =-0.12 p value 0.455 B: 2 sample t test and ci Difference = mean 1st born - mean 2nd born Est of difference:-0.43 95% upper bound for difference: 15.64 T Test of difference 0( vs <) tvue -0.05 p value 0.482 df =16 C. Paired t test and ci 95% ci for mean difference (-8.89, 8.03) T test for mean difference 0 ( vs not 0 ) t value -0.12 p value = 0.911 D. Two sample t test and ci Difference: mean 1st born - mean 2nd born Est for difference: -0.43 95% confidence interval (-19.95, 19.09) T test of difference =0 (vs not =) t value-0.963 df 16
