Question
The table below gives the number of hours spent unsupervised each day as well as the overall grade
averages for five randomly selected middle school students. Using this data, consider the equation of the
regression line, y = bo + bjx, for predicting the overall grade average for a middle school student based
on the number of hours spent unsupervised each day. Keep in mind, the correlation coefficient may or
may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to
use the regression line to make a prediction if the correlation coefficient is not statistically significant.
