Sleep deprivation affects the human brain. One study tested the reaction time of individuals who had been awake for various lengths of time. The table below gives the results. (source: Cain SW, Silva EJ, Chang AM, Ronda JM, Duffy JF)
Use a linear model to predict the reaction time of someone who has been awake for 24 hours.
Based on the model, how many hours awake corresponds with a reaction time of 800 milliseconds?
