Part 3: More reasoning through the big ideas

A researcher is able to gather data from a random sample of students about the average number of hours they sleep per weeknight and the total number of points they earn in their chemistry course. Is there a relationship between amount of sleep and points earned in the chemistry course? The researcher finds that the correlation between these variables is r = 0.44. Further, the regression equation to predict total points earned based on average hours of sleep is as follows:

Predicted total points = -47.3 + 41.10 (average hours of sleep per weekday)
