Julio distributed a survey to his fellow students asking them how many hours they spent playing sports in the past day. He also asked them to rate their mood on a scale from
0
00 to
10
1010, with
10
1010 being the happiest. Julio created the following scatterplot and regression line to show this relationship.
The fitted line has a
y
yy-intercept of
5
55.
What is the best interpretation of this
y
yy-intercept?
Choose 1
Choose 1
(Choice A)
A
The average mood rating was
5
55.
(Choice B)
B
The model indicates that students who spent
0
00 hours playing sports will have an average mood rating of
5
55.
(Choice C)
C
The model indicates that students who had a mood rating of
0
00 will spend approximately
5
55 hours playing sports.
(Choice D)
D
Students who had a mood rating of
0
00 must have spent
5
55 hours playing sports.
A graph plots Mood rating, from 0 to 9, in increments of 1, versus Hours playing sports, from 0 to 4.5, in increments of 0.5, on an x y plane. 7 points rise diagonally in a loose, but narrow cluster between (0, 4.8) and (3, 9.5). A regression line rises diagonally through the center of the cluster from (0, 5) and (3, 9.5). All values estimated.
