0 5 10 15 20 Reading time in hours Language test score in points 120- 100- 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 80- how many hours per month he or she spends reading. Using the sample data, Tatiyana produces a scatterplot with reading time on the horizontal axis and language test scores on the vertical axis. She develops a least squares regression equation where x is the amount of time spent reading during the month and is the predicted value of the language test score. 60- 40- 20- 225 25 Compute the value of when a student spends 38 hours reading. Give your answer precise to one decimal place. Avoid rounding until the last step. y= 3.251x + 31.237 = 148.3 13 Identify all of the true statements regarding the interpretation of when x = = 38. The value of is a predicted value of the language test score if a student reads for 38 hours. the language test score that any student who reads for 38 hours will obtain. the language test score that predicts the reading time to be 38 hours. an unreliable prediction of a language test score because the value of 38 hours is outside the scope of the model. the predicted number of students that read for 38 hours
