Suppose a sleep apnea company wanted to predict the maximum number of hours of sleep needed for those aged 18 and older, how would we make this prediction? Let’s assume the slope of the line is b = -3. The most commonly used criterion to select a line of prediction is called the Choose... criterion. This criterion says: Among all the lines that look Choose... on your data, choose the one that has the Choose... sum of squared vertical deviations. The -3 slope value means that for each additional year in age, the maximum hours of sleep needed Choose... on average by three hours.

Suppose a sleep apnea company wanted to predict the maximum number of hours of sleep needed for those aged 18 and older, how would we make this prediction? Let’s assume the slope of the line is b = -3. The most commonly used criterion to select a line of prediction is called the
least squares
criterion. This criterion says: Among all the lines that look
good
on your data, choose the one that has the
smallest
sum of squared vertical deviations. The -3 slope value means that for each additional year in age, the maximum hours of sleep needed
decreases
on average by three hours.
