A ball is tossed into the air, and the height
of the ball above the ground at different times
is recorded in the table above. A quadratic
regression equation is obtained for these data,
with height expressed as a function of time.
According to the regression equation, what
is the maximum height of the ball?

- While collecting data on shoe sizes (y) compared to heights in inches (x) of male students in the class a student found that the shoe sizes ranged from size 7 to size 11 and the heights of the students ranged from 60 to 72 inches. The student ran a linear regression to get the function = 1 -x- 3 13 where y is the shoe size and is the height of the person in inches. What would be the shoe size for a student who was 73 inches tall? Shoe sizes only show up in incriments of 0.5 (ie. 7, 7.5, 8, 8.5, 9, 9.5, ....) so round to the nearest 1/2 shoe size.
