Question

Managers rate employees according to job performance and attitude. The results for several randomly selected employees are given below. Performance (x) / 2 / 10 / 4 / 6 / 9 / 5 / 1 / 7 / 8 / 3 Attitude (y) / 2 / 1 / 5 / 7 / 4 / 1 / 3 / 9 / 5 / 3 Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. (Enter the slope for full credit.)

Answer 1

Solution :

Given that Performance (x) as 2 , 10 , 4 , 6 , 9 , 5 , 1 , 7 , 8 , 3

Attitude (y) as 2 , 1 , 5 , 7 , 4 , 1 , 3 , 9 , 5 , 3

=> The equation of the regression line is y = 3.200 + 0.145*x

=> slope = 0.145
