Fitting Linear Models to Data · Exercise 15

Draw a scatter plot for the data provided. Does the data appear to be linearly related?

For the following data, draw a scatter plot. If we wanted to know when the temperature would reach 28°F, would the answer involve interpolation or extrapolation? Eyeball the line and estimate the answer.

$$\begin{array}{cccccc}\text{Temperature,°F}& \text{16}& \text{18}& \text{20}& \text{25}& \text{30}\\ \text{Time, seconds}& \text{46}& \text{50}& \text{54}& \text{55}& \text{62}\end{array}$$

Its source prints no answer for this problem, so there's nothing to check against.
