A reseаrcher tests whether screen cоlоr (blue vs. white) аffects prоofreаding accuracy, while accounting for each participant's reading speed and whether reading speed interacts with screen color. The study includes 85 participants, with white as the reference group. H1: Blue screens will produce significantly higher proofreading accuracy than white screens.H2: Faster reading speed will significantly predict higher proofreading accuracy.H3: The effect of reading speed on proofreading accuracy will significantly depend on screen color. Estimate Std. Error t value Pr(>|t|) (Intercept) 30.00 4.00 7.50
