4. Imagine we create simulated data for 83 people. Each "person" in the simulation writes two tests (test 1, test 2). As part of our simulation process - we created true scores, random errors, and observed scores for each person - on each test. The correlation between true scores on the two tests is 0.86. For test 1 observed scores: M =68.00, SD = 13.00, and 0.80. For test 2 observed scores: M = 67.00, SD = 10.00, and r = 0.75. What is the correlation between the observed scores? %3D %3D %3D (a) 0.74 (b) 0.55 (c) 0.67 (d) 0.77
