) After the first exam in a large course, the professor surveyed 14 randomly selected students to determine the relation between
the amount of time they spent studying for the exam and exam score. She found that a linear relation exists between the two variables. The least-squares regression line that describes this relation is . (a) Predict the exam score of a student who studied 2 hours.
(b) Write an interpretation for the slope. (Refer to Lesson 12.2 for this.)
(c) Write an interpretation for the y-intercept, if appropriate. If not appropriate, explain why not. (Again, refer to Lesson 12.2 for this.)
2) In what scenarios would it not make sense to interpret the y-intercept?
26.5 miles in 4 hours is stating 26.5 miles per 4 miles. To find out how far it is in one mile, you can either make a proportion or divide 26.5 miles per mile by 4. Division: 26.5 miles per 4 hours = 6.625 mph Proportions: In one hour, Ashleigh traveled 6.625 miles in 1 hour.
