Answer to Question #291445 in Psychology for Herbini

Question

An educational psychologist believes that an individual’s reading speed (in words per minute)

and general comprehension abilities (scored out of 10) may be related to how well they do on a

timed exam. To study the relative importance of these variables and the association between them,

she runs a multiple regression and produces the following predictive model for exam score:

Exam Score = 7.78 + (0.05*Reading Speed) + (5.77*Comprehension)

Exam Score = 7.78 + (0.05*Reading Speed) +

(5.77*Comprehension) Description - An equation which reads as follows: Exam score = 7.78 add

(0.05 times Reading Speed) add (5.77 times Comprehension)

and a comprehension score of 8?
