Question

The annual geography contest at Keller High School was held last week. The freshman socialstudies teacher handed out study packets a few weeks before the contest and asked all of herstudents to participate. After the contest, the teacher asked the students to report thenumber of hours they spent studying, x, and their score, y. Then, she calculated theregression line for the data:y = 7.1x + 11.3What does the value 11.3 in the equation of the regression line predict?

Answer 1

for y = 7.1x + 11.3

The score of a student who spends no time in studying

Because for zero hours, i,e when x = 0 hours, the student spends no time studying.

Substitute x = 0 in the equation

y = 7.1(0) + 11.3

y = 0 + 11.3

y = 11.3

Final answer

Option A: The score of a student who spends no time studying
