Answer:

Option d

Step-by-step explanation:

Given that a company studying the productivity of its employees on a new information system was interested in determining if the age (X) of data entry operators influenced the number of completed entries made per hour (Y).

[tex]y= 14.374 - 0.145x[/tex]

Suppose the actual completed entries per hour for an operator who is 35 years old was 8, implies [tex]x=35[/tex]

Estimated [tex]y =14.374-0.145(35) \\y =9.299[/tex]

Residual = Actual - estimated =[tex]8-9.299\\=-1.299\\=-1.3[/tex]
