Question
Transcribed Image Text:The accompanying data represent the number of days absent, x, and the final exam score, y, for a sample of college students in a general education course at a large state university Complete parts (a) through (e) below.
(a) Find the least-squares regression line treating number of absences as the explanatory variable and the final exam score as the response variable.
(Round to three decimal places as needed.)
(b) Interpret the slope and the y-intercept, if appropriate Choose the correct answer below and fill in any answer boxes in your choice.
(Round to three decimal places as needed)
OA. For every additional absence, a student's final exam score drops
OB. For every additional absence, a student's final exam score drops
OC. The average final exam score of students who miss no classes is
OD. It is not appropriate to interpret the slope or the y-intercept
(c) Predict the final exam score for a student who misses five class periods
- (Round to two decimal places as needed.)
Compute the residual
(Round to two decimal places as needed)
