An Industrial-Organizational Psychologist wants to use scores on a cognitive ability test (range from 0-7; higher scores indicate more cognitive ability) as a selection criterion for new hires. She collects data by giving a sample of n = 7 current employees a cognitive ability test and compares cognitive ability test scores to the employees' performance evaluation scores (range from 0-20; higher scores indicate better job performance). See her data below. She expects that higher scores on the cognitive ability test are related to significantly (a = .05) higher performance evaluation scores. Cognitive Ability X 6 ΣΧ=31 2 3 4 5 5 6 a = My= Mx= Performance Evaluation Scores Y 10 15 14 16 14 XY 20 20 45 X² 9 16 25 Y² 56 80 70 25 120 36 18 108 36 324 ΣΥ=107 ΣΧΥ = 499 ΣΧ’-151 ΣΥ2 = 1,697 100 225 196 256 Based on your calculations for Step 3 of the correlation, what is the regression equation for predicting performance evaluation scores based on cognitive ability?
