(2 points) Joe has a job skills score that is 1 point higher than Anna's How much higher or lower is his predicted performance rating than Anna's?Explanation / Answer
a) Equattion:
Rating = 2.001 + 0.047 * Skillset
b) x = 97
Rating = 2.001 + 0.047 * 97
Rating = 6.56
c) Higher by 0.047
d) See in model summary table
R is given, this is correlation coefficient
R = 0.463
