Demos ProTip: Did you know that you can copy and paste this table into Desmos?
a) Use technology and all the data points to calculate the regression (best fit) linear model for W. Round your result to the nearest hundredth
W=
b) If I could leave the hospital when I weighed 5 pounds (80 ounces), according to your model, on what day was I allowed to go home (round to the nearest whole
number)?
The model predicts that I was allowed to go home on day
c) really went home on day 24. According to your model, how much did I weigh on day 24 (to the nearest whole ounce)?
The model predicts that on day 24 1 weighed on
