Question
Transcribed Image Text:Suppose Tatiyana is interested in the relationship
y
between language ability and time spent reading. She
120-
randomly selects a sample of 30 students from the
100-
local high school and collects their scores from a
language aptitude test. She surveys the sample asking
80-
each student how many hours per month he or she
60-
spends reading.
40-
Using the sample data, Tatiyana produces a scatterplot
20-
with reading time on the horizontal axis and language
test scores on the vertical axis. She develops a least
5
10
15
20
25
squares regression equation where x is the amount of
Reading time in hours
time spent reading during the month and ŷ is the
predicted value of the language test score.
ŷ = 3.251x + 31.237
Compute the value of ŷ when a student spends 35 hours reading. Give your answer precise to one decimal place. Avoid
rounding until the last step.
