Suppose Tatiyana is interested in the relationship between language ability and time spent reading. She randomly selects a sample of 30 students from the local high school and collects their scores from a language aptitude test. She surveys the sample asking each student how many hours per month he or she spends reading.

Given that, \hat{y} = 3.251x + 31.237 .

Thus, when, reading hours, x = 35,

\hat{y} = (3.251 * 35) + 31.237 = 145.022. (Ans).
