This data set was collected by a college psychology class to determine the effects of sleep deprivation on students' ability to solve problems. Ten participants went 8, 12, 16, 20, or 24 hours without sleep and then completed a set of simple addition problems. The number of addition errors was recorded.

a. Define your variables and create a scatter plot of the data.
b. Write an equation of a line that approximates the data and sketch it on your graph.
c. Based on your model, how many errors would you predict a person to make if she or he hadn't slept in 22 hours?
d. In 10c, did you use interpolation or extrapolation? Explain.
